Technology Coopetition and Voluntary Disclosures of Innovation
Authors: Oh Jun , Yeung P. Eric , Zhu Bo
Published: August 2024

We examine firms’ voluntary disclosures of innovation under technology coopetition, focusing on technology standard setting organizations (SSOs). Technology coopetition is characterized by (1) cooperation to determine technology standards, which requires information sharing to reach consensus, and (2) competition for standard implementation to obtain standard-essential patents, which create incentives for firms to deviate from the expected level of information sharing. We document a decrease in 10-K narrative R&D disclosures, more generic 10-K narrative R&D disclosures, and a longer delay of patent disclosures via the USPTO after a firm joins an SSO. Among alternative explanations, our evidence is most supportive of the hypothesis that firms strategically withhold innovation information.

Published: August 2024

OBJECTIVE

This study aimed to assess the need for practice-wide quality improvement to support evidence-based type 2 diabetes screening for women with a history of gestational diabetes mellitus (GDM) receiving primary care. We sought to add the diagnosis of GDM to the problem list of women who did not have it at baseline.

RESEARCH DESIGN AND METHODS

We identified all women in our practice with a history of GDM diagnosed between 2002 and 2023, quantified the proportion with GDM documented in their problem list, and examined patient- and clinician-level factors associated with having GDM appropriately documented at baseline.

RESULTS

We identified 203 women with GDM receiving primary care within internal medicine. Of the 203 women, 73 (35.0%) did not have GDM documented in their problem list. Of those without GDM included on the problem list, 52% were overdue for type 2 diabetes screening compared with 41% of those with GDM documented before our intervention. We found race, parity, and previous abnormal glycemic laboratory test results to be highly predictive of whether the history of GDM was on patients’ problem list. Upon completion of our intervention, we successfully achieved a 100% documentation rate for GDM diagnosis for women who previously lacked documentation in their problem list.

CONCLUSION

This work paves the way for targeted interventions aimed at improving care for women with a history of GDM, including delivery of interventions and education to prevent the onset of an appropriate clinical screening for type 2 diabetes.

Published: August 2024

Thermoplastic starch (TPS) is a biofilm made from starch and cellulose. The advantage of thermoplastic starch is easily degraded. TPS has weaknesses in high water affinity and low mechanical properties, so it is necessary to add polyvinyl alcohol (PVA) in making TPS packaging. The mechanical properties of TPS-PVA can be further improved by modifying it into a composite with coconut fiber cellulose. This research was purposed to produces a film containing cellulose from coconut fiber as a reinforcing material for film composites as well as to evaluate the biodegradation properties of the resulting film. It is known that the addition of 5% w/v coconut cellulose fiber is the formulation with the best yield when compared with the 1% and 3% w/v formulations. Applying TPS film to chilies can increase the shelf life of chilies. As a product that spoils quickly, one of the efforts made to maintain the quality of chilies is to use packaging made from TPS. Storing chilies at different temperature conditions using TPS-PVA film packaging with the addition of 5% w/v coconut fiber cellulose was able to maintain the shelf life and quality of chilies for 19 days at cold temperatures. Keywords: Chilies, Cellulose, Thermoplastic starch

The  social reality today in rural areas, a wife works to help the family economy, besides having to do domestic tasks. The concept of gender does not prohibit a wife from working. However, this will be a problem if it creates gender inequality. This study aims to reveal the problem of fulfilling domestic duties for career wives in terms of gender perspective. This research is qualitative with the type of literature study, descriptive analytical method with based on a gender approach. The result of this study is that the career wife in fulfilling domestic duties in rural areas based on a gender perspective can be seen from the role that must be carried out. The wife's roles in a gender perspective are: a) mother's role, b) wife's role, c) social role, d) family's motivator. Getting many roles, apart from being a housewife and also having to work is not an easy thing for a wife. This role must be shared with the husband so that it can be balanced so as to create harmony in a household. A woman who already has a role as a mother, wife, member of the community and also has to play a role in the family, but the husband must help and support fully.

Published: August 2024

Majelis taklim (known as taklim assemblies or taklim council) in Central Kalimantan uses different references in conveying and discussing fiqh material. This leads to a mixture of ideologies, for example, there are indications of deception in using fiqh references. Hence, the research aimed to find out the pattern of fiqh references used by Majelis Taklim in Central Kalimantan. It used empirical legal research with a sociological juridical type and a socio-legal approach. The research showed the fiqh references used by the majelis taklim  appear with various ideologies. And, four fiqh reference patterns were found, including the tendentious, the comparative and a mixture of ideologies or non-schools of thought, the pattern with organizational ideology, and the pattern referring towards the Syafi'i school of thought. From the four characteristics, it seems that the tendentious fiqh pattern, either tarjih maqasid or malat al-af‘al, more likely leads to bringing mudharat (negative) and, even, not given benefit for Muslim community as a whole. However, in practice, there are indications of deception that may not be aware of by the public. If this tendentious pattern accepts ideological pluralism would certainly not be problematic. But, in reality, they are seen as splitting-bamboo politics with a scenario according to their interests and status to promote their ideology. Also, it needs to highlight the comparison of fiqh and a mixture of ideologies or non-schools of thought. It is believed that this pattern has its benefits. On the other hand, people who are less well prepared on az-zari‘ah, will deal with their problems, which may lead to ideological chaos.
The effect of game-based learning model with STEM approach in reducing learning anxiety and enhancing science learning motivation among students
Authors: Anggraini Irma Novita , Arif Syaiful
Published: August 2024

Students' anxiety in science learning can affect their overall abilities. Thus, schools must create a supportive environment to reduce anxiety and foster learning motivation. This study examines the influence of game-based learning models with STEM approaches to decrease learning anxiety and enhance students' learning motivation. The study was conducted at the junior high school level, specifically at SMPN 1 Mlarak Ponorogo. The method employed was quantitative descriptive with questionnaire surveys for 34 students. The research findings, analyzed through MANOVA tests, revealed that the game-based learning model with STEM approaches did not significantly affect students' learning anxiety and motivation. Still, it did influence students' learning outcomes. Consequently, this study suggests that employing game-based learning models enhances students' learning outcomes more effectively than conventional teaching methods. The implications of this study underscore the importance of considering non-academic factors in adopting innovative learning models to support effective teaching and learning practices.

Economic Life and Way of Life of Peasants as a Reflection of the Process of Formation of a Rural Settlement Network on the Territory of the Middle Irtysh Region in the Late 19th - Early 20th Century
Authors: Sokolova Evgeniya V.
Published: August 2024

In the process of formation of the rural settlement network of the Middle Irtysh region, several stages can be distinguished, among which an important place is occupied by the period of the late 19th - early 20th century. At this time, a large number of new rural settlements appeared on the map of the modern Omsk region, and the number of existing settlements increased significantly. The circumstances that determine this process within the designated chronological framework are of interest today in the interdisciplinary scientific field. Considering the stated problem, both objective and subjective factors should be taken into account; take into account the influence of state policy, natural and climatic, geographical, socio-economic conditions. One of the indicators of the process of formation of a rural settlement network on the territory of the Middle Irtysh region in the late 19th - early 20th century. the organization of the economic life and life of the peasants. It was they who, in many ways, determined the microclimate in the village or the need to find a new place of residence. The construction and maintenance of the railway, the availability of land, forests and pastures suitable for farming, the availability of sources of drinking water created the conditions for the emergence of new settlements in the Irtysh region. Their foundation was the result of both the resettlement of peasants from beyond the Urals, and the result of internal migration. The basis of economic life was arable farming and cattle breeding. Crafts, which directly depended on the place of residence of the peasants, played an important role in economic life. An important condition for settling in a new place was the construction of houses. The type of dwelling depended on the zone of settlement: in the steppe and forest-steppe zones, the main types of dwellings of the settlers at the first stage were dugouts, huts and booths, in the taiga regions the material for construction was wood.

За даними МОЗ, у нашій країні щорічно реєструють 100–120 тис. осіб, які перенесли гостре порушення мозкового кровообігу (інсульт), 20–40% пацієнтів із цім діагнозом стають залежними від людей, які їх оточують. Порушення рухових функцій є складовою частиною клінічної картини людини з наслідками перенесеного інсульту. Найчастіше спостерігаються порушення рухів однієї половини тіла (геміпарез) або повна їх відсутність (гіміплегія). Найскоріше відновлення втрачених функцій особи з наслідками гострого мозкового кровообігу є одним із пріоритетних завдань комплексної реабілітації таких пацієнтів. У числі багатьох питань, які вирішуються в контексті формування життєво необхідних навичок, є відновлення локомоторної функції людини. Це знижує ступень залежності людини після інсульту від оточуючих та покращує можливості її соціальної адаптації та інтеграції в суспільстві. Мета та завдання дослідження – з’ясувати психолого-педагогічні умови відновлення локомоторної функції в осіб з наслідками гострого порушення мозкового кровообігу з використанням засобів додаткової опори, визначити та обґрунтувати алгоритм формування додаткових опорних пристроїв, особливості їх застосування під час навчання ходьбі на кожному етапі її формування. Проаналізовано особливості застосування додаткових опорних пристроїв під час формування навичок ходьби, розкрито основні чинники, що гальмують процес відновлення локомоторної функції під час використання засобів додаткової опори. Запропоновано методичні прийоми, що прискорюють процес відновлення навички самостійної ходьби. Формування цієї навички має здійснюватися через послідовне формування вмінь і навичок ходьби з використанням у певній послідовності засобів ручної додаткової опори, які підбираються для кожного пацієнта відповідно до типових та індивідуальних особливостей людини, рухового та неврологічного стану. Для підвищення заохочення до занять методичне забезпечення реабілітаційного заняття повинне залежать від індивідуальних особливостей пацієнтів, схильностей та інтересів кожної людини, які визначаються на підставі результатів попереднього психологічного обстеження. Ходьба з кожним із видів опорних пристроїв має свої специфічні особливості, розглядається як окрема рухова дія та має проходити такі стадії, як: початкове розучування, поглиблене розучування, застосування навички в різних умовах (формування варіативних навичок). На стадіях ознайомлення і поглибленого розучування рухової дії навчання елементів кроку незалежно від використовуваного опорного пристрою має проводитися роздільно за фазами, із зупинкою і фіксацією положення після виконання кожної фази рухової дії, що пов’язано з парезом м’язів задньої групи стегна. По мірі вдосконалення навички ходьби надалі дія виконується без акцентування уваги на кожній із фаз.

Red chili (Capsicum annuum L.) is one of  important types of vegetables and also has many varieties that have distinctive colors and shapes, chili is also considerd as one of vegetable that has high economic value. Chili is usually consumed in from of fresh, dried and processed as vegetables and also seasonings, in addition to functioning as a food flavor enhancer. Many obstacles faced by farmers in chili cultivation are plant disturbing organisms such as pests and diseases. Some important pests that commonly attack chili plants are fruit flies (Bactrocera spp), armyworms (Spodoptera litura) and aphids (Aphis gossypii). The purpose of this field practice was to determine the diversity of arthropods and the intensity of pest attacks in Pagaralam City on ten chili fields with different ages. This field practice is expected to provide information about arthropod diversity and attack intensity, especially to farmers as the main actors in agriculture. This insect observation method is carried out using the Diagonal sampling method, Scan sampling (Visual observation) and observing the intensity of the attack. The results of the observations obtained are that the chili farmers have carried out the concept of integrated pest management, but they are not aware of it, and the pests obtained in the field are fruit flies (Bactrocera spp), armyworms (Spodoptera litura) and aphids (Aphis gossypii), and for arthropod diversity it varies on each land.

Published: August 2024

As a logistics organization, the service quality would be considered as one of the evaluating standards of its service. However, it appears with the customers’ satisfaction. Customer satisfaction could be considered as a good way to attract the consumers in choosing and re-choosing such organization. To detect the service quality, SERVQUAL model would be a good choice because it starts from the expectation of the customers and the service perceived. It also divided into five dimensions as tangible, responsiveness, response, assurance, and empathy to test the service quality of an organization. In this model we can get the GAP of the service expectation and perceived in digital form then can find out the real service quality of the organization. Moreover, this research would use Beibu Gulf Port Group as the questionnaire participants (The customers who experienced the service of the group and the staff of the group). The model’s result would show how the service quality of testing sample and then offer improving or maintaining suggestion on it.
PPP infrastructure investments in Brazil: Establishing stylized facts
Authors: Bertulucci Maria Luísa , Pereira Alfredo Marvão
Published: August 2024

Public-private partnerships (PPPs) were established in Brazil at the beginning of this century, following a global trend of using these partnerships to stimulate investment in infrastructures, particularly in a framework of restrictive budgetary and fiscal conditions. Despite their growing importance and the expectation of an expanding role in the future, not much is known about the actual facts on the ground. The objective of this paper is to be a first step in the direction of filling this information gap by providing important stylized facts about the universe of PPPs in Brazil: the quantitative evolution of PPP adoptions; the characterization of the geographical distribution of PPPs by government level (federal, state, district, and municipal); the characterization of the PPP intervention areas, including the total value of contracts and the modalities of PPP concession (sponsored and administrative). This objective is rendered possible by the development of a new database that covers the entire process of PPP contracting from 2005 to 2022, including the opening of public consultation procedures, the publication of the official notice, and the signing of contracts, as well as multiple thematic, financial, jurisdictional, and regional indicators. In turn, we see the establishment of these stylized facts as a necessary first step in the direction of understanding the factors that may determine or condition their adoption. In general, having a clear picture of the universe of the PPPs in Brazil is fundamental as their use and their role are expected to significantly increase in the future as the country pursues a path of improved economic activity and well-being of the population.

Published: August 2024

Frustrated phases in chiral liquid crystalline systems, such as the blue phase (BP) and the twist grain boundary (TGB) phase, can create new opportunities in liquid crystal research. These frustrated phases have unique optical properties which can be used for specific applications. A new binary mixture system composed of a chiral rod-like ferroelectric liquid crystal and an achiral hockey stick-shaped compound was designed. This binary system exhibits induced frustration, resulting in the emergence of the BP-III and TGB*A phases in addition to the chiral ferroelectric Smectic-C* phase. We report a comprehensive study on several binary mixtures (xH-22.5= 0.162, 0.25, 0.396, 0.562) designed of a chiral ferroelectric liquid crystal derived from the lactic acid, namely 4-(octyloxy)phenyl 3-methoxy-4-((4-((2-(pentyloxy)­propanoyl)­oxy)benzoyl)oxybenzoate and achiral hockey stick-shaped compound, namely (E)-4-((E-((3-(decyloxy)-2-methylphenyl)imino)methyl)-phenyl 3-(4-(dodecyloxy)phenyl)acrylate. These mixtures induced the blue phase (BP-III, ~2.5–6.2K) and the twist grain boundary Smectic-A*phase (TGB*A  ~1.8–6K). Polarizing optical microscopy, birefringence, and dielectric spectroscopy were employed to investigate the BP-III and  phases, as those techniques provide insights into their structural and dynamic properties. The ferroelectric behaviour of the SmC* mesophase was investigated by electro-optics. The obtained results are discussed in relation to the molecular structures of the used materials.
Commercially available wearable health monitors in dogs only had a very strong correlation during longer durations of time: a pilot study
Authors: Hilborn Erin C. , Rudinsky Adam J. , Kieves Nina R.
Published: August 2024

OBJECTIVE

To compare a commercially available accelerometer, FitBark 2 (FitBark 2nd Generation; FitBark) with a previously validated accelerometer, Actical (Actical; Respironics Inc) during periods of activity and rest. We hypothesized that the FitBark 2 would correlate strongly with the Actical during periods of activity and rest.

METHODS

20 dogs between the ages of 1 and 9 years of variable sex, breed, and body weight were enrolled from April through August 2022 in a 1-week pilot trial. Dogs were fitted with a neck collar with both devices mounted on it and wore it continuously for 1 week. Six time points were established to evaluate varying degrees of activity and periods of rest, which included the week, a 1-mile walk, the day of the walk, the hour the walk occurred in, 6 am to 7 am on the morning of the walk, and 11 pm to 12 am on the evening of the walk. Actical and FitBark 2 were compared using linear regression and correlation analysis.

RESULTS

Correlation analysis revealed a very strong correlation between the Actical and FitBark 2 during the entire week of the study, with a moderate correlation at other time points. Linear regression revealed the strength of the relationship by the r2 = 0.85, F1,13 = 76.08.

CONCLUSIONS

FitBark 2 can be used to evaluate the activity and rest of dogs with varying degrees of correlation when compared to the Actical.

CLINICAL RELEVANCE

The time period assessed impacts the correlation of the FitBark 2 and Actical. This should be considered when using the FitBark 2 for data collection.
Characterisation of the lipolytic enzymatic activities of fungal rizoenzymes from Rhizopus oryzae in comparison to pancreatin from pigs
Authors: Schön C. , Wacker R. , Rothe M. , Lipowicz B. , Iphöfer A.
Published: August 2024

Aim

In case of exocrine pancreatic insufficiency (EPI), the replacement of digestive enzymes with, for example porcine pancreatin or fungal rizoenzymes, is unavoidable under certain conditions. Current guidelines indicate that preparations from porcine pancreas have more advantageous physicochemical properties compared to those from fungi, especially at high bile salt concentrations, and that the latter can, therefore, only be used clinically to a limited extent. Since rizoenzymes are increasingly used in clinical practice, the present in vitro study investigated efficiency of enzymatic activity of rizoenzymes in comparison to pancreatin under various physiological and partly extreme environmental conditions.

Materials and Methods

The lipolytic properties of two typical preparations containing digestive enzymes from porcine pancreatin and rizoenzymes were compared (same dosage of activity units) at different pH values (pH 3–9), with the addition of different bile salt concentrations (0–15 mmol/L sodium taurocholate). Lipolytic activity was measured by quantifying the fatty acids released from olive oil substrate by liquid chromatography–tandem mass spectrometry after enzymatic digestion.

Results

For both enzyme preparations, the lipolytic activity maximum was reached at pH 7 with comparable fatty acid conversion rates (57% pancreatin, 58% rizoenzymes). However, in contrast to pancreatin, rizoenzymes were already active for certain fatty acids from pH 3 to 4. At a bile salt concentration up to 10 mmol/L taurocholate, there was an increase in activity of both enzyme preparations (rizoenzymes 69% vs. pancreatin 58% enzymatic conversion). Only at rather unphysiological concentration of 15 mmol/L during EPI, there was a slight decrease in activity (to 56%) for the rizoenzymes.

Conclusions

Rizoenzymes are an alternative therapeutic option for EPI. Relevant differences between rizoenzymes and pancreatin with regard to lipolytic activity under different physicochemical conditions could not be demonstrated in this study, whereas a potential advantage in favor of rizoenzymes activity at already low pH values was observed.

Published: August 2024

Environmental challenges related to plastic waste underscore the urgent need for innovative solutions. Polyhydroxyalkanoates (PHA) have emerged as sustainable alternatives to conventional plastics, particularly in packaging, due to their biodegradability and biocompatibility. However, the cost of PHA production and certain physical limitations compared to synthetic polymers remain significant barriers to widespread adoption. Within this context, Actinophytocola algeriensis, an Actinobacteria species isolated from the Sahara desert in Algeria, holds promise for its biotechnological potential and bioactive molecules. Despite this, our understanding of its enzyme profile, notably the PHA synthase (EC 2.3.1.304), the key enzyme in PHA biosynthesis, remains limited. In this study, the 3D structure of PHA synthase was modeled utilizing the artificial intelligence program AlphaFold, followed by the structural refinement and validation. In addition, physicochemical properties and functional characterization were conducted using various bioinformatics tools. This research signifies a substantial advancement in comprehending the molecular mechanisms underlying PHA biosynthesis in A. algeriensis, thereby fostering the development of innovative biotechnological applications for sustainable biopolymer production.

The purpose of this study is to determine the effect of travel agencies' reservation systems and online transaction capacities on their competitiveness. With the developments in technology and the integration of these developments in all business areas, travel agencies have also had to benefit from information and communication technologies. In the research, the primary data were used, and the data were collected by the questionnaire method. The convenience sampling method was used, and data were collected from a total of 566 travel agency managers in Istanbul. According to the results of the research, reservation systems and online transactions capacities of travel agencies affect their competitiveness. Reservation systems and online transactions capacities of travel agencies affect their competitiveness in specific issues such as cost, service quality and market share. Although appropriate and enlightening results were obtained regarding travel agencies technological capacity and competitiveness, research was carried out on the perceptions and evaluations of the managers in this study. In this context, in future studies, studies can be conducted on the relationships between measurable quantitative variables such as the online transactions of travel agencies and the capacity and transaction volume of reservation systems and competition structures. The study reveals that the traditional office travel agencies should be more successful than their competitors in terms of reservation systems and online transaction capacities to gain affordable cost, quality service and more market share.

Tensile loads can occur due to various factors, one of which is due to earthquakes and wind. The tensile load acting on the building will be resisted by foundations such as ground anchors and bored pile. In this study, an analysis was carried out to design the tensile bearing capacity of ground anchors and bored pile as a barrier to tensile forces on buildings. The load used in designing ground anchors and bored pile is the reaction of a 33-story building. The analysis is carried out on the bearing capacity of the ground anchor with bored pile that will be installed on the raft foundation according to the position of the column point. The result of the analysis is a design comparison between ground anchor and bored pile in terms of dimension and bearing capacity. The analysis found that bored piles require a shallower soil depth than ground anchors to achieve bearing capacity according to the building's tensile reaction. However, in terms of the components in the ground anchor that contribute to the tensile bearing capacity, the ground anchor is superior in terms of tensile capacity per depth to bored pile.

Beban tarik dapat terjadi akibat berbagai faktor, salah satunya akibat gempa dan angin. Beban tarik yang bekerja pada bangunan akan ditahan oleh fondasi seperti ground anchor dan tiang bor. Pada penelitian ini, dilakukan analisis untuk mendesain daya dukung tarik ground anchor maupun tiang bor sebagai penahan gaya tarik pada bangunan. Beban yang digunakan dalam mendesain ground anchor dan tiang bor adalah reaksi dari bangunan 33 lantai. Kondisi muka air tanah pada lokasi bangunan berada pada permukaan tanah karena terletak di pinggir pantai. Analisis dilakukan terhadap daya dukung ground anchor dengan tiang bor yang akan dipasangkan pada fondasi raft sesuai dengan posisi titik kolom. Hasil analisis merupakan perbandingan desain antara ground anchor dengan tiang bor secara dimensi dan daya dukung. Dari hasil analisis, didapatkan bahwa tiang bor membutuhkan kedalaman tanah yang lebih dangkal daripada ground anchor untuk mencapai daya dukung sesuai reaksi tarik bangunan. Namun secara komponen pada ground anchor yang berkontribusi kepada daya dukung tarik, ground anchor lebih unggul secara kapasitas tarik per kedalaman daripada tiang bor.

In the modern world, there is a clear phenomenon of impoverishment of legal science due to its disengagement from ethics, which must remain present and intact in the elaboration, interpretation and application of laws. Starting from the dimensions that surround the analysis of a crime (philosophical, political and legal-scientific), does the crime of evasion tax must aim at legal protection of the Treasury or the fundamental and solidarity duty of Paying taxes? Pay taxes, for the purposes of its configuration in the field of criminal law? The objective of this article is to analyze, even if superficially, the criteria of interpretation and application of the ethical foundations of taxation Western, since life in a society democracy requires citizens to fully exercise of fiscal solidarity, given its fundamental duty to pay taxes, depending on their economic capacity, for the achievement of the common good, so that whoever does not do so, intentionally, is committing a conduct deserving of criminal reproach.
