Authors: Ratnasari Emma Dwi , Susilowati Indah , Maria Nugroho Sumarjiyanto Benedictus
Published: August 2023

Purpose: This study aims to study the vulnerability of farmers' livelihoods as a result of shifts in slow and fast variables.
 
Method: In this study, the Livelihood Vulnerability Index (LVI) approach and the Photovoice method were used to comprehensively describe and analyze the vulnerability of farmers' livelihoods. The Livelihood Vulnerability Index LVI method will provide a deeper understanding of the level of vulnerability of farmers to these changes. In addition, the Photovoice method is used to obtain a visual perspective from the farmers themselves.
 
Results and conclusion: The results of this study reveal that the vulnerability of farming households in coastal areas is in two aspects. First, through the Livelihood Vulnerability Index (LVI), it can be seen that land conversion has resulted in a decrease in the productivity of the agricultural sector, farmer incomes, and loss of livelihoods for vulnerable local farmers. The sensitivity of farmers is also evident through their high dependence on the agricultural sector and their reluctance to leave their homes. Second, using the Photovoice method, the sources of vulnerability faced by farm households are illustrated, such as water and soil contamination by shrimp pond waste and decreased productivity and income due to careless disposal of waste.
 
Research implication: The vulnerability of farmers' livelihoods is also affected by limited capital and lack of compliance with agricultural governance regulations, increasing the vulnerability of farmers in the coastal areas of Kebumen.
 
Originality/value: Livelihood vulnerability is an important concept in understanding the extent to which farmers are vulnerable to social, economic and ecological changes.

Purpose: Purpose of this research is to carry out a machine learning intelligence based innovative method to determine quality of food which may be hazards to health if consumed by humans. This article detects human sickness by sensing nutrition that causes smells.
 
Theoretical framework: In developing nations, people just focus on basic need of food rather than focusing on the quality and the nutritional values of food which are exhibiting hazards impact of unhealthy food on the lives of people. Many people are suffering from diabetics, cancers, cardiac problem, liver problems and stomach related health issues which are originated due to consumption of bad food. Consumers are satisfied with food quality, and more individuals are assessing it.
 
Method/design/approach: As a methodology, an electronic nose uses chemical sensors to identify complicated odors. Standard technologies can detect gases from households, industries, and explosive materials. It cannot fulfill freshness requirements. Electronic noses, computer vision, and other sensory approaches may imitate human olfactory, taste, visual, and sensory qualities, both pleasantly and unpleasantly. Neural networks organize innovative artificial/mechanical intelligence systems to interpret fragrance recordings for human brain recognition. Inspired by human brain processing, we offer optimized feedback, centroid clustering, and self-organizing maps for machine learning systems to identify smell data. This work proposes a simulation technique based on benchmark datasets to achieve high type accuracy, precision, and recall for diverse scented records where additional information may be artificially/mechanically found. The centroid SOM research of olfaction involves investigating more physiologically and nutritionally feasible methods for mapping, understanding, and interpreting massive scent datasets for real-world applications.
 
Results and conclusion: In all analyzed result and conclusion, the accuracy, precision, and recall of the clustering centroid with optimized feedback SOM are superior to the existing clustering approach. By simulating the data on different set of test and train data it has observed that Proposed (Cluster Centroid with SOM ) method is effective than the existing (Centroid) method. For example, 10% of test data existing method has 67.55% of accuracy and proposed method has 86.75% which is shown in result and conclusion section in details.
 
Research implications: The research makes an effective contribution by demonstrating the potential and the need to adopt sustainable practices in the management of contemporary companies.

Dietary fiber analysis of D-allulose added cakes and determination of microbiological changes during storage
Authors: ORAN Ceyda , BARCIN İpek , ÖZGÜR Elif Büşra , ÖZGÜR Mustafa
Published: August 2023

D-Allulose is a monosaccharide that is rarely found in foods and can be obtained commercially by enzymatic reactions and isolation from bacteria. It can not be absorbed because of its chemical composition's resistance to digestive enzymes. It is referred to as a "energy-free natural sweetener" for this reason. These findings has led to an increase in D-allulose usage in the food industry. In this study, the total dietary fiber of cakes with additional D-allulose was determined, as well as the microbiological changes that occurred during storage. Three distinct cakes were made for the trial as the control (sugar), 50% sugar plus 50% D-allulose, and 100% D-allulose. In the baked cakes, dietary fiber analysis was done on day 1 and microbiological analyses were done on days 0, 7, 14, and 21. On the first day of analysis, there was no difference between the groups in the total spor-forming bacteria counts of the cake groups, but on the 7th, 14th, and 21st days of analysis, there were statistically significant differences between the groups (p0.05). The control group's total dietary fiber content were 5.93 g/100 g, and AL 100 group’s content were 10.70 g/100 g. D-Allulose is regarded as a natural sweetener with significant antimicrobial properties and a high dietary fiber content.
Plea Bargaining System as a Non-Litigation Settlement In The Framework of Repositioning Criminal Justice In Indonesia
Authors: Almi Ara Annisa
Published: August 2023

In its development, Plea Bargaining was accommodated into a written rule in 1970, when the court decided the case of Brady v United States. The Plea Bargaining System uses methods in civil law to resolve criminal cases. Indonesia's legal system can adopt the Plea Bargaining concept into the criminal justice system. The drafting team introduced the term Plea Bargaining in the Academic Paper of the Draft Criminal Procedure Code (NA RUU KUHAP). This design is considered different from the initial concept applied in other countries. Therefore, an analysis of legal protection and certainty for justice seekers (justiciabelen) is needed. The research method used is normative juridical, namely by studying secondary data and understanding law as a set of rules related to Plea Bargaining.
The Authority Of The DPR On The Appointment and Dismissal of Constitutional Judges
Authors: Prasetyo Iwan Kurniawan , Azzahra Humaira , Huda Khazanatul
Published: August 2023

Based on the 1945 Constitution, 3 institutions are authorized to appoint constitutional judges, including the Representative Council, Supreme Court, and the President. In the event that the dismissal of constitutional judges can be carried out if they have fulfilled the criteria contained in article 23 of Law No.7/2020. Paragraph (4) of the same article confirms that those with authority to dismiss a constitutional judge are the Chief Justices of the Constitutional Court and the President. However, in 2022 there is a polemic, namely the form of intervention against the dismissal of constitutional judges carried out by one of the legislative bodies, namely the Representative Council of Indonesia, which is a big question mark. What kind of authority does the Representative Council have as a legislature over the CC? Is this action justifiable and in accordance with applicable law? This legal research with a normative juridical approach examines secondary data in books, journals, and legislation as a reference. The result of this study indicates that the Representative Council’s over CC as contained in the 1945 Constitutions is very limited in proposing 3 candidates for constitutional judges and has no authority at all to dismiss them. The Representative Counsil’'s decision to dismiss constitutional judges is an act of offending the principle of the independence of the Constitutional Court and has no legal basis.
Acquisition of Customary Rights of Customary Communities In Customary Lands for Corporate Business Use Rights
Authors: Pratama Arya Putra Rizal , Wulandari Sinar Aju
Published: August 2023

Indonesia has regulations on land management related to the economy based on the public interest. The use of land by a corporation is carried out by granting cultivation rights (HGU) over the ground through a Government stipulation. However, with increasing investment activity, land has become essential to support capital inflows in Indonesia. With the shift in land requirements for investment, customary land has become an attraction for investors in business activities in the agricultural, fishery or plantation sectors. This research is legal research (doctrinal analysis) using a conceptual approach (conceptual approach) and statutory approaches (statute approach). The results of this study explain that the use of land in corporations located on customary land through HGU is a legal action and can be carried out as long as it does not interfere with or eliminate the essence of the characteristics of the customary land rights. Then, granting HGU over customary land can be done in consultation with the customary community with corporations through the government. However, the deficiency in granting HGU over customary land when this period expires threatens the loss of the status of customary land and customary rights.

Published: August 2023

The physiology of rocket plants at different salinity levels through irrigation water and leaching fractions was assessed. Four salinity levels of irrigation water: 0.10, 1.60, 3.10 and 4.60 dS m-1 and three leaching fractions: 0, 10 and 20% were applied. The physiological variables analyzed were photosynthetic rate, stomatal conductance, transpiration rate and photosynthetic pigment contents. The growth and biomass production were analyzed by: plant height, number of leaves, leaf area and partitioned and total plant fresh and dry mass, and root to aerial part ratio. The leaching fraction of 10% combined with irrigation with water salinity levels ranging from 0.10 to 0.88 dS m-1 resulted in greater plant height, leaf area and root, shoot and total dry mass. The leaching fraction of 20% with irrigation water with salinity levels from 0.10 to 2.7 dS m-1 generates higher leaf number, shoot fresh mass, root-to-shoot ratio, stomatal conductance, and photosynthetic rate. Irrigation water with a salinity level of 0.10 dS m-1 provides a higher transpiration rate for rocket plants. Irrigation water with a salinity level of 4.6 dS m-1 generates higher chlorophyll a, b and total (a + b) and carotenoid contents in rocket plants.

El delirium posoperatorio (DPO) es una entidad clínica de alta frecuencia, entre 20% a 75%, en pacientes mayores a 65 años. En general es una entidad subdiagnosticada a pesar de ser la primera causa de complicación posoperatoria. Prácticamente, no existen datos en los servicios hospitalarios nacionales al respecto, a pesar de ser una entidad que tiene gran impacto en costos en salud, y en morbimortalidad. En la literatura se ha reportado que la detección precoz puede reducir la frecuencia de delirium posoperatorio al menos 40%. Este estudio realizó un diagnóstico de la frecuencia del delirium posoperatorio en el hospital Base San José de Osorno, en base a la evaluación del estado cognitivo de pacientes mayores de 65 años con menos de 48 h posoperados. Se utilizó test CAMs long form. Resultados: Se evaluó a 58 pacientes (39 hombres y 19 mujeres) en las primeras 48 h posoperados, de los servicios de cirugía general, neurocirugía, traumatología, urología, oftalmología y otorrinolaringología, que correspondió al 38,16% de los posoperados del mes en que se realizó el estudio. Se encontró una frecuencia global de 51,72% de pacientes con CAM S alterado. con 93,3% de la variedad hipoactiva. Conclusión: Este estudio logra confirma las frecuencias internacionales de DPO, y reafirma la necesidad de crear programas integrales de detección precoz de la fragilidad cognitiva preoperatoria y diagnóstico posoperatorio en los centros de salud de Chile para disminuir las complicaciones asociadas a esta patología.

CoeffNet: Predicting activation barriers through a chemically-interpretable, equivariant and physically constrained graph neural network
Authors: Vijay Sudarshan , Venetos Maxwell , Spotte-Smith Evan , Kaplan Aaron , Wen Mingjian , Persson Kristin
Published: August 2023

Activation barriers of elementary reactions are essential to predict molecular reaction mechanisms and kinetics. However, computing these energy barriers by identifying transition states with electronic structure methods (e.g., density functional theory) can be time-consuming and computationally expensive. In this work, we introduce CoeffNet, an equivariant graph neural network that predicts activation barriers using coeﬀicients of a frontier molecular orbital (such as the highest occupied molecular orbital) of reactant and product complexes as graph node features. We show that using coeﬀicients as features offer several advantages, such as chemical interpretability and physical constraints on the network’s behaviour and numerical range. Model outputs are either activation barriers or coeﬀicients of the chosen molecular orbital of the transition state; the latter quantity allows us to interpret the results of the neural network through chemical intuition. We test CoeffNet on a dataset of SN2 reactions as a proof-of-concept and show that the activation barriers are predicted with a mean absolute error of less than 0.025 eV. The highest occupied molecular orbital of the transition state is visualized and the distribution of the orbital densities of the transition states is described for a few prototype SN2 reactions.
Comprehensive analysis of relaxation decays from high-resolution relaxometry
Authors: Bolik-Coulon Nicolas , Zachrdla Milan , Bouvignies Guillaume , Pelupessy Philippe , Ferrage Fabien
Published: August 2023

Relaxometry consists in measuring relaxation rates over orders of magnitude of magnetic fields to probe motions of complex systems. High-resolution relaxometry (HRR) experiments can be performed on conventional high-field NMR magnets equipped with a sample shuttle. During the experiment, the sample shuttle transfers the sample between the high-field magnetic center and a chosen position in the stray field for relaxation during a variable delay, thus using the stray field as a variable field. As the relaxation delay occurs outside of the probe, HRR experiments cannot rely on the control of cross-relaxation pathways, which is standard in high-field relaxation pulse sequences. Thus, decay rates are not pure relaxation rates, which may impair a reliable description of the dynamics. Previously, we took into account cross-relaxation effects in the analysis of high- resolution relaxometry data by applying a correction factor to relaxometry decay rates in order to estimate relaxation rates. These correction factors were obtained from the iterative simulation of the relaxation decay while the sample lies outside of the probe and a preceding analysis of relaxation rates which relies on the approximation of a priori multi-exponential decays by mono-exponential functions. However, an analysis protocol matching directly experimental and simulated relaxometry decays should be more self consistent. Here, we introduce Matching INtensities for the Optimization of Timescales and Amplitudes of motions Under Relaxometry (MINOTAUR), a framework for the analysis of high-resolution relaxometry that takes as input the intensity decays at all fields. This approach uses the full relaxation matrix to calculate intensity decays, allowing complex relaxation pathways to be taken into account. Therefore, it eliminates the need for a correction of decay rates and for fitting multi-exponential decays with mono-exponential functions. The MINOTAUR software is designed as a flexible framework where relaxation matrices and spectral density functions corresponding to various models of motions can be defined on a case-by-case basis. The agreement with our previous analyses of protein side-chain dynamics from carbon-13 relaxation is excellent, while providing a more robust analysis tool. We expect MINOTAUR to become the tool of choice for the analysis of high-resolution relaxometry.
WS2 fullerene/plate nanofibers: the tunable crossroad between dimensionalities
Authors: Kundrat Vojtech , Kral Zdenek , Pinkas Iddo , Pinkas Jiri , Yadgarov Lena
Published: August 2023

Our work describes the nanofibrous materials of tungsten disulfide, which can be tuned by the precursor's crystallinity degree. The carefully formulated nanofibers create the morphological crossroad between fullerenes (0D), nanotubes (1D), plates (2D), and a nonwoven web of nanofibers (3D), containing all the advantageous properties of the presented material categories. Our synthetic methodology (electrospinning, reductive sulfidation) allows scale-up to industrial production. In addition, we studied the optical properties of the WS2 nanofibers using extinction and absolute absorption measurement. The results of the optical analysis further indicate the higher crystallinity of the closed stacked fullerene-based structure. By comparison of the extinction with the absorbance, we find that all the examined nanostructures display typical polaritonic spectra. However, the open plate structure exhibits a stronger scattering and thus better pronounced polaritonic features. Moreover, the ability to control the morphology allows for variating polaritonic features of the final nanofibrous material, which can directly impact the potential optoelectronic and photocatalytic applications.
Macroscopic Approach to Cloud Droplet Growth by Condensation - A Study by a semi-real scale Experimental System
Authors: masahiro utiyama , tsutom fukuyama
Published: August 2023

Formation and growth of water droplets were studied using a semi-real scale experimental system; the main component of the system was a 430 m vertical shaft used to perform cloud formation experiments at a spatial scale close to that of the real atmosphere. By generating an updraft with humid air, a cloud was observed to form at a height of 35 m from the bottom. The number concentration, and size distribution of water droplets were recorded. In some experiments, NaCl particles were intentionally injected into the air stream to increase the number of condensation nuclei. The effects of this on the number and size distribution of droplets were studied. The droplet growth rate was estimated on the basis of these effects. It was found that in the shaft, the humidity of the air stream was below the saturation level. Thus, macroscopically, condensation and growth proceeded without supersaturation, which is usually assumed in traditional microscopic cloud physics for water droplet growth. The growth process was considered as a chemical reaction to deal with this condition. An attempt was made to obtain information about the rate constant.

Published: August 2023

The precise control of the regioselectivity in the transition metal-catalyzed migratory hydrofunctionalization of alkenes remains a big challenge. With a transient ketimine directing group, the nickel-catalyzed migratory β-selective hydroarylation and hydroalkenylation of alkenyl ketones has been realized with aryl boronic acids using alkyl halide as the mild hydride source for the first time. The key to this success is the use of a diphosphine ligand, which is capable of the generation of a Ni(II)-H species in the presence of alkyl bromide, and enabling the efficient migratory insertion of alkene into Ni(II)-H species and the sequent rapid chain walking process. The present approach diminishes organosilanes reductant, tolerates a wide array of complex functionalities with excellent regioselective control. Moreover, this catalytic system could also be applied to the migratory hydroarylation of alkenyl azahetereoarenes, thus providing a general approach for the preparation of 1,2-aryl heteroaryl motifs with wide potential applications in pharmaceutical discovery.

Появляются новые виды товаров и услуг, видоизменяется сам образ жизни. В данных условиях необходимым и своевременным является вопрос изучения обозначенных современных трендов и тенденций. В статье представлены результаты авторского междисциплинарного исследования «Успешность современного человека: модель его удовлетворенности», которое было реализовано в ряде российских регионов. Оно показало, что одним из определяющих стимулов потребления сегодня является ориентация на удовлетворенность. Поэтому необходимо определить взаимосвязь между структурой покупок, возможностями индивида, рациональностью расходов, стилем потребления и другими влияющими друг на друга факторами для возможности осуществить оценку данным явлениям и определить детерминантные факторы удовлетворенности, которые претерпевают изменения вследствие влияния на них экзогенных и эндогенных составляющих (факторов). Анализу данных вопросов посвящена данная статья.

Целью работы явилось поиск и выработка новых путей развития государственно-частного партнерства (ГЧП) в Российской Федерации на современном этапе развития в эпоху крупнейшей санкционной атаки на страну государствами коллективного Запада. Предметом проведенного исследования были определены, как экономические взаимоотношения между государством и обществом, через институты ГЧП в период ускоренных процедур импортозамещения и формирование института параллельного импорта на государственном уровне. Методология проведенной работы основана на кабинетном исследовании и сравнительном анализе. В рамках проведенной работы результаты показали, что в настоящее время направление ГЧП по сфере розничной торговли должно становиться столь же актуальным для экономического развития регионов страны и национальной экономики, как и направления импортозамещения и институт параллельного импорта, в связи с необходимостью активизации вопросов стимулирования спроса у потребителей на отечественную продукцию и аналоги дружественных стран, а также легализацию института параллельного импорта в связи с введенным крупным пакетом санкций странами коллективного Запада. Областью применения результатов являются рекомендации по выработке мер для ответственных за это ведомств на федеральном и региональном уровнях по вопросам трансформации национального института ГЧП. В связи с этим в качестве выводов проведенного исследования стоит сформулировать, что данное направление теоретических обоснований данного явления, в настоящий момент находящееся на начальной стадии рассмотрения, также должно стать в ближайшие годы актуальным, а возможно, и одним из ведущих в национальной экономической теории России.

Authors: Пилипенко Игорь Валерьевич
Published: August 2023

В статье рассматривается проблема сравнения динамики и результатов жилищного строительства в 15 республиках СССР за 45-летний период, которой в российской научной литературе до недавнего времени уделялось мало внимания. На основе составленной автором базы данных по более чем 120 союзным и республиканским статистическим сборникам предлагается авторский метод сравнения, включающий расчет 89 показателей, характеризующих ввод жилых домов по республиках, в городских поселениях и в сельской местности, по источникам финансирования (государство, население, жилищно-строительные кооперативы и колхозы), размер жилищного фонда в городских поселениях и сельской местности; динамику построенных квартир / домов; число жителей, улучшивших свои жилищные условия. В первой части статьи приводятся общие результаты расчетов по республикам, а также рейтинги РСФСР с выделением случаев вхождения республики в тройку лучших по 89 показателям. Во второй части статьи представлены результаты вычислений индикаторов для 14 остальных союзных республик.

Özet Bu araştırmanın genel amacı; Isparta ilinde bulunan Milli Eğitim Bakanlığı’na bağlı devlet liselerinde 2017-2018 eğitim öğretim yılında görev yapan öğretmenlerin görüşlerine göre liselerde örgütsel özdeşleşme (ÖÖ) ile örgütsel
muhalefet (ÖM) arasındaki ilişkinin incelenmesidir. Bu genel amaç kapsamında, liselerde görev yapan öğretmenlerin ÖÖ’ye ilişkin görüşlerinin “uyum” , “özdeşleşme” ve “içselleştirme” boyutlarında ve ÖM ilişkin görüşlerinin “dikey
muhalefet” , “yatay muhalefet” ve “dışsal muhalefet” boyutlarında nasıl olduğunu, lise öğretmenlerinin ÖÖ’ye ve ÖM’e ilişkin görüşlerinin; cinsiyet, kıdem, okulda çalışma süresi, okulda çalışma nedeni, eğitim durumu ve okul türü
değişkenlerine göre farklılaşıp farklılaşmadığını ve ÖÖ’nin, ÖM’in anlamlı bir yordayıcısı olup olmadığını incelemek amaçlanmıştır. “Örgütsel Özdeşleşme Ölçeği” ve “Örgütsel Muhalefet Ölçeği” kullanılmıştır. Genel tarama modellerinden
ilişkisel tarama modeli kullanılmıştır. Araştırmanın örneklemini 291 lise öğretmeni oluşturmaktadır. Elde edilen veriler SPSS 22.0 ile çözümlenmiştir. Verilerin analizinde betimsel istatistiklerden frekans, yüzde, aritmetik ortalama
ve standart sapmadan yararlanılmıştır. Öğretmen görüşleri üzerinde karşılaştırma ve ilişki analizlerinde anlam çıkarıcı istatistiklerden bağımsız örneklemler T-testi, tek yönlü varyans analizi (One-way ANOVA) ve çoklu doğrusal
regresyon analizi kullanılmıştır. Araştırma sonuçlarına göre, lise öğretmenlerinin ÖÖ ve ÖMe ilişkin görüşleri orta düzeydedir ve çeşitli demografik değişkenlere göre öğretmen görüşleri farklılaşabilmektedir. İki değişkenin boyutları
arasında anlamlı ilişki saptanmış ve ÖÖ’nin özdeşleşme boyutunun ÖM’in dikey muhalefet boyutunu ve ÖÖ’nin uyum boyutunun ÖM’in yatay muhalefet boyutunu anlamlı bir şekilde yordadığı tespit edilmiştir.
Developing The Environmental Attitudes of Secondary School Students With Virtual Education Application and Their Metaphorical Projections

Çevresel sorunlar her geçen gün çoğalmakta dünyamızı ve insan sağlığını tehdit etmektedir. Bu tehditler karşısında hemen herkesin çevresel anlamda bir tutum geliştirmesi kritik öneme sahiptir. Bu nedenle bu çalışma bireylerin erken
yaşlarda çevresel tutum kazanmaları üzerine yoğunlaşmaktadır. Bu bağlamda sanal gerçeklik gözlükleri aracılığıyla oluşturulan basit bir eğitim ortamının öğrencilerin çevresel tutumlarını geliştirip geliştiremediği test edilmiştir.
Bu amaç doğrultusunda yapılan bağımlı örneklem t-testinde olumlu sonuçlar elde edilmiştir. Başka bir ifade ile sanal eğitim uygulaması öğrencilerin çevresel tutumlarının gelişmesine katkı sağlamıştır. Bu nicel verinin desteklenmesi
adına çalışmaya katılan öğrencilerinden nitel veriler metaforlar yardımıyla elde edilmiştir. Öğrencilerin çevre kirliliği, su israfı ve küresel ısınma ile ilgili algıları yüz yüze görüşmeler ile toplanmıştır. Çevre kirliliği ile
ilgili dikkat çeken metaforlar “kendine zarar verme, kirlenmiş hayat, yok oluş” olarak tespit edilmiştir. Su israfı ile ilgili dikkat çeken metaforlar “hayatın israfı, çocukların hüznü, akan kan” dır. Küresel ısınma ile ilgili
de “yok olma, çölleşme, ektiğini biçme” metaforları dikkat çekmektedir. Çalışmaya katılan öğrencilerde aldıkları sanal eğitim uygulamasına paralel şekilde gelişme tespit edilmiştir. Bu gelişmenin öğrencilerin ürettikleri metaforlarda
görülebildiği araştırmacının kanaatidir. Bu veriler ışığında eğitim ortamlarında sanal eğitim uygulamalarına daha sık yer verilmesi gerektiği karar alıcılara ve öğretmenlere önerilebilir.

There is a growing interest in the use of Design Thinking (DT) to enrich re-quirements elicitation processes. This fact motivated us to explore the use of the Brainstorming technique, usually used alone for requirements elicitation, in combination with user-centered and empathy-oriented techniques taken from the DT process. Specifically, we carried out a quasi-experiment to com-pare the Effectiveness of Brainstorming sessions in terms of the number of ideas of requirements generated, and also the Identified Stakeholders, com-plementing the Brainstorming sessions with two of the most widely used DT techniques: Empathy Maps and Personas. Therefore, we consider three treatments: Personas + Brainstorming, Empathy Maps + Brainstorming, and Brainstorming alone (control group). The quasi-experiment was carried out with 74 students enrolled in the Bachelor of Computer Engineering course at the Universitat Politècnica de València in 2021. The results reveal a statisti-cally significant effect on Identified Stakeholders when using Empathy Maps. Descriptive analysis shows also an increase in Identified Stakeholders when using Personas, and in the Effectiveness of Brainstorming sessions when used together with Empathy Maps or Personas. There is also a variation in the type of ideas, with the number of functional ideas being higher, and that of non-functional ideas being lower when Empathy Maps are used. These re-sults seem to indicate that Brainstorming sessions are improved when com-plemented with Empathy Maps or personas techniques. However, we still do not have enough evidence to recommend either Personas or Empathy Maps. Therefore, further experimentations will be needed to obtain more conclu-sive results considering some improvements that are discussed in the paper.

Published: August 2023

The rapid evolution of information technology in the software industry has led to challenges in Requirements Engineering, impacting the academic landscape. Recent studies identify risks to system quality and project success due to industry-specific processes. Professionals trained in academia face a disparity between market practices and academic teachings, resulting in significant knowledge gaps. To address this, a study engaged requirements engineers from Brazilian software development companies. Their experiences were gathered through a survey, focusing on requirements documentation problems and the challenges newcomers face. The study also identified specific knowledge areas that require reinforcement. The findings underscore the need to address significant knowledge gaps. It was concluded that industry practices in requirements engineering differ from documented literature, affecting professional training. Additionally, there is a demand for greater transparency within the industry, and professionals expressed a strong interest in bridging the gap and improving the current situation.
