Accesul studenților pe piața muncii: valorificarea primelor experiențe profesionale [Articol]
(Universitatea de Stat din Moldova, 2026) Deleu, Ecaterina
Studiul vizează specificul tranziției tinerilor de la studii la piața muncii, așteptările și dificultățile pe care le au în cadrul stagiilor de practică și experiențelor de angajare în domeniu. Cercetarea a fost realizată în cadrul Facultății de Jurnalism și Științe ale Comunicării (USM) și pune accent pe necesitățile de capital uman pe care le are presa într-un context marcat nu doar de războiul din Ucraina, dar și de războiul hibrid, de emigrația tinerilor – care fac extrem de dificilă reziliența redacțiilor. În cadrul cercetării au fost organizate la începutul anului de studii, timp de trei ani consecutiv, o serie de evenimente: lecții de profesionalizare, dezbateri și ateliere cu absolvenți ai facultății, cu studenți angajați în redacții; punându-se accent pe angajarea în domeniu, pe metoda peer learning, pe schimbul de experiență și valorificarea primelor experiențe profesionale. Pe lângă chestionarea tinerilor, a fost aplicată observația participativă, metoda analitică și metoda behavioristă.
From the fear of isolation to the fear of exposure: reinterpreting the spiral of silence theory in the platform society [Articol]
(Universitatea de Stat din Moldova, 2026) Tacu, Mariana
The transformations produced by digitalization, platformization, and algorithmic mediation reconfigure the mechanisms for forming and expressing public opinion. The Spiral of Silence theory, formulated by Elisabeth Noelle-Neumann, explains the dynamics of self-censorship through the perception of the majority and the fear of social isolation. In the context of the platform society, these mechanisms are reshaped by the economy of visibility, the logic of digital metrics, as well as online reputational sanctions. With in this conceptual framework, the notion of the Exposure Spiral is outlined, which describes self-censorship driven by fear of public exposure and digital stigmatization. At the same time, the introduction of the concept of algorithmic public opinion highlights the role of technological infrastructure in shaping the perception of the majority and in shaping contemporary discursive behavior.
Podcastul digital ca exponent al soluțiilor inovatoare în domeniul sustenabilității [Articol]
(Universitatea de Stat din Moldova, 2026) Rusnac, Ludmila; Guțu, Vitalie
Rolul mediului digital în promovarea dezvoltării durabile este unul incontestabil. Platformele media digitale se proiectează tot mai pregnant ca instrumente de educație ecologică. Datorită accesibilității, contentele injectate în mediul online devin virale în foarte scurt timp, or interactivitatea asigurată de mediul digital antrenează implicarea cetățenilor în activități de informare, de inițiere și implicare în protejarea mediului. În conținutul acestui articol sunt analizate modalitățile de popularizare în mediul digital a tehnologiilor verzi și a unui mod de viață sustenabil. Investigăm o serie de podcasturi ce au avut un impact considerabil în conștientizarea adoptării unui comportament responsabil în raport cu mediul. Articolul oferă o analiză critică asupra modului în care podcastul influențează percepțiile publice despre sustenabilitate și comportamente ecologice.
Identification of quality productive common wheat varieties in unfavorable environmental conditions [Articol]
(Technical University of Moldova, 2026) Jelev, Natalia
Background: The reduction in crop yields under unfavorable climatic conditions in recent years has led to enormous losses, both in terms of food supply for the population and livestock, and for the national economy. Unfavorable conditions negatively affect the productivity and quality of seeds, especially during dry summers, particularly at the stages of wheat flowering and maturation. The country is forced to import high-quality wheat from other countries, as the wheat varieties cultivated domestically, both in previous years and at present, do not ensure the maintenance of quality under these conditions. These factors constitute the main causes of economic losses recorded in years with unfavorable climatic conditions. The cause of this situation lies in the irrational use of wheat varieties cultivated in the country in relation to these extreme climatic conditions. From the above, it follows that there is an urgent need to identify, within the country, varieties that can ensure productivity and grain quality at an optimal level, meeting domestic requirements. Aim of the study: Identification of productive and quality varieties under unfavorable conditions. Materials and methods: In this study, seeds of six hexaploid wheat varieties (Kuialnic, Meleag, Moldova 5, Moldova 66, Moldova 614, and Bijuteria Zâmbrenilor) were used, cultivated on the experimental field of the Institute of Genetics, Physiology, and Plant Protection of the ASM during 2024–2025. At full maturity, the seeds of these plants were harvested and analyzed to determine productivity and quality, by evaluating the yield, gluten content, and gluten quality. The data obtained were statistically processed using the ANOVA software package, calculating mean values and standard deviations, as well as significant differences among the varieties. Key results: The analysis of dry gluten content in different common winter wheat samples revealed differences among the varieties. The highest dry gluten content was recorded in the Moldova 66 sample, approximately 14%, indicating superior quality gluten with high potential for premium bakery products. The Moldova 5 and Kuialnic samples also showed high values, ranging between 12.5% and 12.7%, suggesting gluten with good dough-forming and baking properties.Moderate values, between 11.0% and 12.1%, were observed in the Meleag, Moldova 614, and Bijuteria Zâmbrenilor samples, indicating a gluten content suitable for standard bakery products. The results reflect genetic differences among the varieties and allow the identification of those with the greatest potential for use in the baking industry. Regarding the harvest, no significant differences were observed among the samples. Conclusions.The analysis of wet and dry gluten content in different common winter wheat samples revealed significant differences among the varieties. The Moldova 66 and Moldova 5 samples stood out with the highest gluten values, indicating high potential for premium bakery products. Samples with moderate values, such as Kuialnic, Moldova 614, Meleag, and Bijuteria Zâmbrenilor, exhibited gluten suitable for standard bakery products. The results confirm the influence of variety genetics on gluten quality and allow the selection of samples with the greatest potential for the baking industry.
Investigation of non-Saccharomyces yeast biodiversity and their persistence across vintages and winemaking stages in moldovan vineyards [Articol]
(Technical University of Moldova, 2026) Zgardan, Dan; Mitina, Irina; Mitin, Valentin; Grajdieru, Cristina; Rubtov, Silvia; Balanuta, Anatol
Background: Historically, non-Saccharomyces yeasts were considered spoilage organisms in winemaking. Recent research, however, recognizes their ability to enhance wine complexity, improve aromatic profiles, and provide bioprotection by suppressing undesirable microbes. Aim of the study: This study aims to investigate the diversity and persistence of nonSaccharomyces species in several Moldovan vineyards, assessing their presence across three vintages and two vinification stages to better understand their role in terroir-driven wines. Material and methods: Four sets of wine samples were collected at two key stages - initial must and mature wine - from three grape varieties: Feteasca Neagră, Feteasca Albă, and Nistreana, grown in four Moldovan viticultural areas: Purcari, Strășeni, Mileștii Mici, and Chișinău. Vinification was performed under controlled conditions at the micro-winery of the Technical University of Moldova using traditional protocols. Must samples were taken before commercial yeast inoculation, and mature wine samples just before bottling. DNA was extracted using the SDS-PVP method with bead-beating, followed by real-time PCR (qPCR) with SYBR Green and custom primers targeting 16 species: Torulaspora delbrueckii, Candida stellata, Hanseniaspora occidentalis, Hanseniaspora vineae, Hanseniaspora uvarum, Lachancea kluyveri, Lachancea thermotolerans, Metschnikowia pulcherrima, Meyerozyma guilliermondii, Pichia farinosa, Pichia fermentans, Pichia membranifaciens, Pichia occidentalis, Pichia terricola, Wickerhamomyces anomalus, and Zygoascus meyerae. Results: Screening showed that 5 of the 16 target species appeared in at least one sample: H. uvarum, M. pulcherrima, M. guilliermondii, P. occidentalis, and P. terricola. H. uvarum was the most prevalent yeast, detected in 100% (12/12) of must samples and 83.3% (10/12) of finished wines across all vintages. Conclusions: These results highlight the native microbial ecology of Moldovan vineyards, showing that some non-Saccharomyces yeasts survive fermentation and persist in the final wine. Their stability suggests potential use as bio-tools to enhance the typicity and quality of regional wines and support the unique sensory identity of Moldovan viticulture.
