Police_hu as a best practice: Online reputation management of the Hungarian Police on Instagram
Authors: Uricska Erna
Published: April 2022

The findings of studies carried out by Google show that 22 percent of the organisations and companies searched for themselves online in 2001. The figure was 56% in 2013, so it can be assumed that this proportion will be even higher in 2021. In the digital age a new concept, an essential professional and social skill is emerging – online reputation management. It is not indifferent what type of digital footprint has been left behind in online space, and it is not only true for citizens, but also for companies and organisations, and for the police as well, nowadays. The aim of reputation management is to make the overall picture of the organisation well-known and influence it positively.  The use of policing social networking sites is applied between the police as a service provider organisation and the members of the community, and there is a chance for sharing and getting real time information.  As a result, policing social networking sites bear utmost importance for citizens, journalists and press officers as well. Police officers not only seek to share information but persuade the citizens to cooperate. The limited importance of textual content can be seen and in parallel, the visual content has become more important. It can be stated that the members of community do not expect a quantitative, but a qualitative presence. Thus, it is the number and quality of comments that reveal how deeply users have been involved in the topic and its imagery content. This study deals with the Instagram profile of the Hungarian Police (police_hu) between July 3, 2019 and July 3, 2020. Applying the method of discourse analysis, the research characterises the most popular and most commented entries during the one-year period. As a result, it can be said that the process taking place on the Instagram of the Hungarian Police implements a kind of brand building, which can be considered a positive example of police communication, while the characteristics of policing digilect can be well observed and analysed.
Creating Sentiment Dictionaries: Process Model and Quantitative Study for Credit Risk
Authors: Mengelkamp Aaron , Koch Kevin , Schumann Matthias
Published: April 2022

Since textual user generated content from social media platforms contains valuable information for decision support and especially corporate credit risk analysis, automated approaches for text classification such as the application of sentiment dictionaries and machine learning algorithms have received great attention in recent user generated content based research endeavors. While machine learning algorithms require individual training data sets for varying sources, sentiment dictionaries can be applied to texts immediately, whereby domain specific dictionaries attain better results than domain independent word lists. We evaluate by means of a literature review how sentiment dictionaries can be constructed for specific domains and languages. Then, we construct nine versions of German sentiment dictionaries relying on a process model which we developed based on the literature review. We apply the dictionaries to a manually classified German language data set from Twitter in which hints for financial (in)stability of companies have been proven. Based on their classification accuracy, we rank the dictionaries and verify their ranking by utilizing Mc Nemar’s test for significance. Our results indicate, that the significantly best dictionary is based on the German language dictionary SentiWortschatz and an extension approach by use of the lexical-semantic database GermaNet. It achieves a classification accuracy of 59,19 % in the underlying three-case-scenario, in which the Tweets are labelled as negative, neutral or positive. A random classification would attain an accuracy of 33,3 % in the same scenario and hence, automated coding by use of the sentiment dictionaries can lead to a reduction of manual efforts. Our process model can be adopted by other researchers when constructing sentiment dictionaries for various domains and languages. Furthermore, our established dictionaries can be used by practitioners especially in the domain of corporate credit risk analysis for automated text classification which has been conducted manually to a great extent up to today.
If you are late, you are Beyond help: Disinformation and Authorities in Social Media
Authors: Alaraatikka Milla , Koistinen Pekka , Kaarkoski Miina , Huhtinen Aki , Sederholm Teija
Published: April 2022

Fast paced, seemingly vast and ever-growing social media is a challenging environment for public authorities to communicate optimally. One challenge is malicious disinformation, which is intentionally disseminated to deceive and cause harm to citizens and authorities. It is known that exceptional circumstances create opportunities for malicious actors to negatively influence democratic societies. Disinformation is often designed to cause uncertainty towards information that public authorities offer and to decrease the overall trust in public authorities. The aim of disinformation is often to cause polarisation in society and to weaken national security. Furthermore, in a crisis, it is essential that authorities are able to deliver official information quickly, clearly and accurately to citizens. Communication between authorities and citizens in time-sensitive situations is typically online. One challenge to public authorities is how they can mitigate and repair the effects of disinformation and information influencing in complex and time-sensitive circumstances. In this article, our aim is to describe the challenges that public authorities face when communicating in social media spaces where disinformation is present. The empirical data, including 16 government official interviews, was collected in September 2021. The main theme of the interviews was related to how situational awareness about disinformation is formed in their organisations. Our research questions focus on how public authorities detect and counter disinformation in social media and what kind of problems and pressures they have when communicating in such environments. This study follows a qualitative design and the data was analysed using inductive content analysis. This study is part of larger project related to counterforces and the detection of disinformation.  The results will provide a broader understanding of how different types of public authorities, from health to security organisations, and from agencies to ministries, communicate in complex environments such as social media.
Communication of Slovak eco-innovation companies with social media users
Authors: Kubovics Michal , Zaušková Anna , Ščepková Simona
Published: April 2022

Social media is widespread worldwide and firmly defined in today's communication. Available resources point to dynamic changes in consumer behavior, to which even ecologically oriented business entities must respond. Therefore, it is appropriate and necessary to look for innovative solutions that will contribute to improving the communication of eco-innovative businesses with their followers on social communication platforms. The aim of the paper is to map and describe the current state of communication of the responded Slovak eco-innovation companies with social media users. The communities that are emerging on social media are the driving force behind today's market environment. Communities can be talked about in connection with the pressure they exert on eco-innovation businesses, entities and other business areas. At the core, the authors focus on the interpretation of partial results from their own pilot survey, which serves as an input survey for mapping the current communication and will be a key basis for subsequent research. The interpreted findings from the survey come from a quantitative survey using a standardized questionnaire, which was answered by a total of 142 respondents, who represent representatives of Slovak eco-innovation business entities. From the author's research, we can define which digital platforms use subjects to communicate with their followers, how often they communicate with them, through what type of contributions and with what frequency they publish contributions. The results indicate reserves in the given issue. For this reason, further research and education of subjects is important. The limits of the investigation are in a smaller number of business entities and in the possibility that business entities did not provide true information. The authors of the article did not come to the conclusion that someone would carry out a similar survey within the Slovak eco-innovation entities, and therefore they point to the results of their own pilot survey. Eco-innovation entities do not currently have information on the communication process with their followers on social media. The authors consider the interpreted results from the pilot survey to be original and necessary due to the absence of marketing statistics, which would subsequently help businesses to set up the right online marketing strategy.
contribution of SNS to social capital in times of restricted physical contact
Authors: Hooper Val , Duffy-Bregmen Tayla
Published: April 2022

Social capital is the collection of social assets and resources that provide value to an individual and on which they can rely in times of need. Social networking sites (SNS) have contributed significantly to the development of social capital. A common classification of social capital is into bridging, bonding and maintained social capital. Often social capital is built and maintained in the online and offline environments together but each environment can foster social capital separately. With the constraints on physical contact and interactivity brought about by Covid-19-related restrictions, the assumption is that there would be greater reliance on SNS to develop and maintain social capital.

This research examined whether, in an environment of ongoing restricted physical social contact, the use of SNS contributes positively to the establishment and development of social capital; and whether the use of different SNS exert different influences on the establishment and development of social capital. SNS use was assessed in terms of frequency and intensity of use; and social capital was assessed in terms of bridging, bonding and maintained social capital. Three SNS (Facebook, Instagram and WhatsApp) were studied. A cross-sectional survey of 282 New Zealand residents was used to gather the data, and regression analyses were conducted to analyse the data.

Findings indicated that frequency and intensity of use were key contributors to social capital, contributing mostly towards bridging social capital and the least towards bonding social capital. Additionally, intense and frequent use of Instagram contributed most towards bridging and maintained social capital, whereas intense and frequent use of WhatsApp contributed most towards bonding social capital.

The research contributes to the theoretical understanding of the role of SNS, particularly with regard to the building and maintenance of social capital but also against a background of restricted physical social contact. It is furthermore of benefit to managers who have - and can - embraced the use of SNS to build and maintain team cultures, especially in terms of Covid-19-related contact restrictions.
E-MINT: A Gamified App for Empowering Parents in Their Role as STEM Gatekeepers

Published: April 2022

When it comes to initiatives engaging children - especially girls - in STEM education or careers, parents are often a neglected group, despite being regarded as the most important gatekeepers in this field because they can have an impact very early on. They frequently feel under-informed and, as a result, lack the self-confidence to take on this role. The E-MINT project starts here and aims to motivate parents and equip them with the skills to serve as role models and mentors to their children.

The Science Capital approach, a proven successful framework for creating awareness, fostering motivation and imparting knowledge in the context of science education, serves as the structural basis of the E-MINT app. This especially applies to the content and functionalities of the app, which is divided into four areas:

“What you know”. In this section, parents are encouraged to explore their own knowledge of STEM professions, gender stereotypes, career choices, educational pathways and future technologies.

“How you think”. In this part of the app, career aspirations, behaviour in different situations or thoughts about the future are told in short picture stories.

“What you do”. The app provides free access to virtual E-MINT Makerspaces. Parents can use the app to complete projects on 3D printing, environmental technology and upcycling at home.

“Who you know”. In this section of the app, parents are encouraged to use their own personal social network to improve their skills as STEM gatekeepers for their children. They are guided step by step through a social network analysis with the aim of visualising their personal STEM networks and finding ways to expand it.

The pre-survey showed parents to be well informed. Parents were most likely to lack information about new technologies and STEM education. In the post-survey, the usability of the app was rated as very good. The comparative survey on parents' STEM knowledge showed slight changes. Parents in the post-survey knew more about training opportunities for STEM professions, about the disproportion of men and women in technical professions and the importance of gender stereotypes for career decisions. Parents' views also changed slightly in the post-survey. Specifically, their attitudes towards computer games, which they now see as having more potential to increase children's digital curiosity, and they see computer games more as a gateway into technical professions.

Published: April 2022

Healthcare professionals’ harness social media to encourage responsible behaviour during the COVID-19 pandemic. As internet users often struggle assessing the veracity of the information in these addresses, acoustic characteristics of the presenters’ speech may play a significant role in their persuasiveness impact. Using a netnographic approach, we studied YouTubers’ reactions to explore the persuasiveness attributes of COVID-19 related speeches included in YouTube videos within a South Africa context. The persuasiveness index was computed from the view count, likes and dislikes of 314 speech segments from YouTube interviews related to COVID-19. Standard acoustic features – Mel frequency cepstral coefficients - of the interviewees’ voice were extracted through speech processing. Recurrent neural networks were optimized and evaluated the strength of these acoustic features to classify and predict the persuasiveness index. The cepstral feature set yielded a balanced accuracy of 86.8% and F1 score of 85.0%. These preliminary results exhibit the potential of the vocal cepstrum as predictor of persuasiveness in healthcare addresses on responsible behaviour during the COVID-19 pandemic. The results imply that quantitative acoustic analysis of a presenter’s voice, independent from text, can explain the impact of social media addresses.
impact of music on the effectiveness of Facebook ads
Authors: Lupa-Wójcik Iwona
Published: April 2022

Facebook is the most popular social media platform in Poland. As a result, it is often used in advertising campaigns by various types of organizations. The effectiveness of these campaigns depends on many factors, including advertising creation. Video ads are dynamic and may contain music. Music in advertising can be aimed at audience attention, persuasion, user interest and sales. Music influences the emotions of the audience, and these are an important factor in making a purchase decision. It can also increase the rememberability of an ad. Its beat is important, as well as content matching. On the other hand, social media audiences may not play music in ads, which often happens when quickly browsing applications such as Facebook, especially on mobile devices. The lack of background music in the video can therefore also make a difference. The aim of the article is to determine the impact of music on the effectiveness of Facebook ads. As a research method the test of four advertising campaigns was used. The video ads differed only in the background music (the remaining settings and the creation of the ads were identical): the first had no musical background, the second had rock music timed with the video beat, the third - the same rock music not timed with the video beat, and the fourth one had a calm music as background music, less suited to the content (the video required rather dynamic music). It has been hypothesized that music or the lack of it in the video ad, its type and timing (or not) with the beat of the ad’s video have an impact on the effectiveness of the Facebook ads. It affects, among others on the reach metric, impressions, post engagement, number of clicks on the ad, cost of clicks, click rate, video plays and video plays costs.

Published: April 2022

Therapeutic music is one of the strategies widely adopted as a complementary therapy, proven by its relevance as a strategy to reduce pain, decrease the level of anxiety and increase adherence to treatment, especially in critically ill hospitalized patients. The application of complementary practices in critically ill patients has been introduced in many Intensive Care Units (ICU) as their benefits are evidenced both in biopsychosocial well-being and in the spiritual sphere. This work is a survey of articles whose objective was to characterize the scientific production on the application of Music Therapy. The main search source was in the databases indexed in the Biblioteca Virtual de Saúde (BVS) and Scientific Electronic Library Online(SciELO). In order to reduce the damage caused by painful procedures and the permanence in an exhausting environment such as the ICU, full of alarms, lights and other noises, many professionals seek a way to humanize through various integrative and non-pharmacological therapies.

Novel Approach of Removing Externally Attached Debris from Animal Carcass to Ensure Meat Safety and Byproduct Quality
Authors: Sarker Majher , Liu Cheng-Kung
Published: April 2022

In this study, a formulation and technique are developed to be used for cattle carcass decontamination prior to removal of hide in a commercially preferred time-frame to ensure meat safety and byproduct quality. This formulation offers deep cleaning on carcass surface by removing debris including manure/mud balls which are firmly attached to the hair of animal hide harboring pathogens like Salmonella and Escherichia coli. Survival of such pathogens can facilitate cross-contamination of the underlying meat and meat-processing equipment in the packing plant posing a challenge to the meat industry as well as public-health. Also, the attached adobe type mud/manure balls have potential to create holes on the hide during leather processing which degrades byproduct’s quality. Formulation was sprayed on cattle’s hide and the attached debris were brushed off from the surface. The formulation was found very efficient in cleaning the hide surface both at 5 and 8 min treatments. The highest of aerobic, Escherichia coli and Salmonella populations were reduced by 8.71, 3.63 and 3.19 Log CFU/50 in 2 , respectively when compared to water-wash. The efficacy of formulation can be optimized by adjusting its concentration and treatment time. Post-leather analysis showed no detrimental impact on byproduct caused by the formulation.

Published: April 2022

It is well known that possible undesirable defects in finished leathers can result from microbial activities on the salted raw hides/skins during storage. The traditionally used salt curing method can control bacterial activities on the raw stock, but it does not seem possible to completely eliminate microbial attacks. Moderately halophilic bacteria can cause serious damage to hides/skins. From this point of view, potential procedures such as applying new antibacterialagents in the leather industry should be considered. Since some lichen species have been indicated for their promising biological efficacies in the literature; most researchers have focused on their potencies in various fields including leather industry from ancient times. In this study, the bacterial growth of proteolytic and lipolytic Gram-negative moderately halophilic bacteria, Chromohalobacter canadensis (YN6) and Halomonas eurihalina (BL5), from saltedsheepskin samples were tested with the extracts of Usnea sp., Plastismatia glauca, Ramalina farinacea, Evernia divaricata, Bryoria capillaris, Hypogymnia tubulosa, Pseudevernia furfuracea and Lobaria pulmonaria. Some of these lichen species were found to be successful to inhibit the bacterial growth of C. canadensis (YN6) and H. eurihalina (BL5). In conclusion, lichen extracts may be utilized in stacked raw hides/skins in tanneries or warehouses to control moderately halophilic bacteria which causes several defects on leather.

Published: April 2022

El contenido de ADN nuclear en tejido foliar de tres poblaciones silvestres de Agave angustifolia y dos de Agave rhodacantha del municipio de Nácori Chico, Sonora, México, se determinó mediante citometría de flujo. Todos los especímenes en las dos especies fueron diploides (2n = 2x = 60). El contenido promedio 2C-ADN nuclear fue de 8.499 pg (1Cx = 4165 Mpb) en A. angustifolia y de 8.415 pg (1Cx = 4124 Mpb) en A. rhodacantha. El contenido promedio 2C-ADN de las tres poblaciones de A. angustifolia y una de A. rhodacantha (El Bajío) fueron iguales, pero estadísticamente diferentes de la población de Los Mochomos de A. rhodacantha. Los cariotipos de las poblaciones de A. angustifolia de Los Mochomos y El Chorro, mostraron el mismo citotipo (48m + 2sm + 6st + 4t), el cual fue diferente en El Bajío (42m + 4sm + 10st + 4t). Las dos poblaciones de A. rhodacantha tuvieron el mismo cariotipo (40m + 6sm + 4st + 10t). La longitud total del genoma (LTG) y el índice de asimetría (TF %) variaron significativamente entre las poblaciones de las dos especies de agave, con excepción de LTG entre las poblaciones de A. rhodacantha. Los valores de LTG fueron mayores en A. rhodacantha que en A. angustifolia y en TF % ocurrió lo contrario. Estos resultados se consideran básicos para el desarrollo de estrategias biotecnológicas y mejoramiento genético de estas especies.

Published: April 2022

Para determinar la genética de la resistencia en tres genotipos de trigo duro (Triticum turgidum var. durum) resistentes a la raza BBG/BN de roya de la hoja (Puccinia triticina E.), se hicieron cruzas de genotipos susceptible x resistentes y resistentes x resistentes, al usar como susceptible a ‘Atil C2000’. La segregación de las progenies en la generación F3 indicó que los genotipos resistentes ‘Syria 1740’ y ‘CMH82A.1062’ poseen dos genes dominantes complementarios (1:8:7) que condicionan la resistencia. La segregación de una familia resistente, dos familias segregantes, una familia susceptible (1:2:1) en el cultivar ‘Creso’ indicó  que la resistencia fue conferida por un gen dominante. En las cruzas resistentes x resistentes se observó que en ‘Syria 1740’ x ‘Creso’ y ‘Creso’ x ‘CMH82A.1062’, las proporciones de cada cruza se ajustaron a la proporción fenotípica 63:1, que indica que la resistencia está condicionada por tres genes dominantes independientes en ambos casos, lo que sugiere que los genes de ambos progenitores segregaron independientemente en cada cruza. Tanto ‘Syria 1740’ como ‘CMH82A.1062’ al ser cruzados con ‘Atil C2000’ exhibieron dos genes dominantes complementarios que condicionan la resistencia. Por la ausencia de familias homocigóticas susceptibles en la cruza de ‘Syria 1740’ x ‘CMH82A.1062’, se infiere que los genes que poseen ambos progenitores son los mismos.

La cutícula cubre la superficie de los frutos y una de sus funciones es la de restringir la pérdida de agua en forma de vapor, por medio de sus características físicas y químicas. En este trabajo se determinaron los cambios ocurridos en la cutícula durante la ontogenia de los frutos de mango (Mangifera indica L.), de los cultivares ‘Tommy Atkins’, ‘Kent’ y ‘Keitt’. Los frutos fueron muestrados al azar de un huerto ubicado en Navojoa, Sonora, México. El estudio se hizo en dos fases: durante el crecimiento de los frutos y en el almacenamiento. Se utilizó un diseño completamente al azar con tres repeticiones y el muestreo realizado fue aleatorio. En cada muestra se determinaron las variables: contenido de ceras (epicuticulares e intracuticulares) y cutina, masa y grosor de cutícula, y ultraestructura y permeabilidad de la cutícula durante la ontogenia del fruto. Los resultados indicaron diferencias entre cultivares. El contenido de ceras epicuticulares se incrementó en todos los cultivares durante el crecimiento del fruto y en el almacenamiento presentó cambios a través del tiempo de la evaluación. En promedio, la cutina representó entre 60 y 80 % de la masa total de la cutícula y el resto correspondió a las ceras cuticulares. La ultraestructura de las ceras cuticulares mostró diferencias varietales en la cosecha: ‘Tommy Atkins’ y ‘Kent’ presentaron mayor proporción de zonas cristalinas (82.6 %) mientras que en ‘Keitt’ fue principalmente amorfa (74.1 %). La mayor eficiencia de la cutícula en regular la pérdida de agua, se observó al momento de la cosecha y se relacionó con la ultraestructura y el contenido de las ceras cuticulares.

Analisa Serangan Remote Exploit pada Jaringan Komputer dengan menggunakan Metode Network Forensic
Authors: Ardiyasa I Wayan
Published: April 2022

Kejahatan siber merupakan aktifitas kejahatan dengan menggunakan perangkat komputer atau jaringan komputer yang menjadi alat, sasaran atau tempat terjadinya kejahatan yang menjadi ancaman terhadap privasi data atau informasi maupun kerugian secara bisnis. Kejahatan siber saat ini semakin meningkat yang disebabkan oleh keterbukaan suatu informasi dan mudahnya akses informasi diinternet. Adanya celah keamanan (vulnerability) pada sistem dan jaringan komputer menyebabkan sistem berpeluang besar menjadi target serangan siber seperti serangan Remote Exploit. Serangan Remote Exploit merupakan serangan yang dilakukan melalui jaringan dengan mengeksploitasi celah keamanan tanpa adanya akses terlebih dahulu kedalam sistem target. Serangan Remote Exploit bertujuan untuk mendapatkan akses kedalam komputer target untuk mencuri data didalam komputer target.

Pada era yang serba digital saat ini, Augmented reality menjadi tren pada beberapa bidang. Pengertian augmented reality sendiri adalah sebuah teknologi yang dapat menggabungkan objek virtual dengan objek yang ada pada dunia nyata secara realtime. Augmented Reality berbeda dari Virtual Reality dan Mixed Reality. Marker base augmented reality merupakan jenis augmented reality yang menggunakan pengenalan gambar 2 dimensi secara real-time untuk memberi pengguna visualisasi data digital tambahan untuk memberikan informasi sesuai yang dibutuhkan. Fast Corner Detection merupakan sebuah algoritma yang diciptakan karena visualisasi realtime yang tidak cukup cepat dan memiliki source komputasi yang tidak terbatas.

Abstrak – Program Beras Miskin atau Raskin merupakan salah satu program pemerintah untuk mengurangi beban pengeluaran dan perlindungan terhadap keluarga miskin melalui pendistribusian beras dengan jumlah dan harga tertentu. Dalam pendistribusian Raskin di desa manggena’e sering kali ditemui kendala atau permasalahan karena masih dilakukan secara manual sehingga memungkinkan terjadinya penentuan secara subyektif oleh pihak pemerintah kelurahan dan belum mengacu pada kriteria yang telah ditentukan. Pada penelitian ini dibangun sistem pendukung keputusan untuk menentukan penduduk yang berhak menerima beras miskin dan penduduk yang benar-benar membutuhkan. Dalam penelitian penentuan penerimaan beras Raskin untuk keluarga tidak mampu menggunakan metode SAW (Simple Additive Weighting). SAW merupakan penjumlahan terbobot dari nilai kinerja pada setiap alternatif pada semua atribut dan membutuhkan proses normalisasi matriks keputusan (X) ke suatu skala yang dapat diperbandingkan dengan semua nilai alternatif yang ada sehingga dapat membantu pihak Kelurahan Kota Uneng dalam menentukan penduduk yang berhak menerima beras miskin dan penduduk yang benar-benar membutuhkan. Dengan demikian diharapkan penyaluran bantuan akan tepat sasaran. Hasil tersebut kemudian dapat ditampilkan berdasarkan nilai terbesar atau terkecil, sehingga memudahkan pengambil keputusan untuk memilih alternatif terbaik dari sejumlah alternatif.

BABACAN LİDERLİK VE YÖNETİCİYE GÜVEN İLİŞKİSİNDE GÜÇ MESAFESİ, BİREYCİLİK VE TOPLULUKÇULUĞUN DÜZENLEYİCİ ETKİLERİNİN İNCELENMESİ

Babacan liderliğin kültürel değerlere göre olumlu ya da olumsuz bir liderlik biçimi olup olmadığının sorgulandığı bu çalışmada, babacan liderlik ve yöneticiye güven ilişkisi ile bu ilişkide kültürel değerlerden güç mesafesi, bireycilik ve toplulukçuluğun düzenleyici etkilerinin olup olmadığının incelenmesi amaçlanmıştır. Bu doğrultuda nicel bir araştırma yürütülmüş ve farklı sektörlerde faaliyet gösteren 753 çalışan anket tekniği vasıtasıyla araştırmaya dâhil edilmiştir. Bulgular çalışanların babacan liderlik algıları ile yöneticilerine duydukları güven arasında yüksek şiddette pozitif bir etkileşimin olduğunu ortaya koymaktadır. Bu ilişkide bireycilik ve toplulukçuluğun herhangi bir düzenleyici etkilerine rastlanmazken, güç mesafesinin negatif fakat oldukça zayıf bir etkisinin olduğu görülmüştür. Değişkenlerin boyutları arasındaki etkileşimler detaylı incelendiğinde ise, babacan liderliğin işyerinde aile atmosferi oluşturma boyutu ile yöneticiye güvenin duygusal güven boyutu arasındaki ilişkide bireyciliğin pozitif düzenleyici etkisi gözlenmiştir. Diğer yandan babacan liderliğin bireysel ilişkiler kurma ve bağlılık beklentisi boyutlarının yöneticiye güven ile ilişkilerinde toplulukçuluğun pozitif düzenleyici etkilerine rastlanmıştır. Sonuç olarak bu çalışmada babacan liderliğin çalışanların yöneticiye duydukları güveni güçlendirdiği, fakat bu ilişkilerde sahip oldukları kültürel değerlerin kayda değer etkilerinin olmadığı tespit edilmiştir. Genel olarak değerlendirildiğinde bulguların yazında konuyla ilgili teorik ima ve farklı görüşlere somut bir dayanak oluşturabileceği belirtilebilir. Bu bağlamda çalışmanın liderlik, örgütsel psikoloji ve kültür alanlarına katkı sağlaması beklenmektedir.

We study how information delivered by teachers to parents on students’ learning progress and guidelines for active involvement in children's education can improve learning outcomes. We conducted a randomized control trial experiment in 130 primary schools in Kebumen District, Central Java, Indonesia. The implementation of the intervention collided with the school closures due to the COVID-19 pandemic, adding to the significance of this intervention to help parents in undertaking learning from home. We find that the intervention increased parental involvement at home and communication with teachers. The information also improved parental demand to teachers which increased teachers’ motivation and support in students’ learning. However, the positive impacts on parents and teachers did not translate into improved student numeracy test scores. Further investigation revealed that parents' low capability to teach their children and the lack of right support given by teachers to students during learning from home hindered the impact on learning outcomes.
