Published: March 2024

The research aim is to provide empirical and theoretical solutions for certain criticalities in the framework of Integrated Implementation Reporting (IIRF) within the context of higher education. Indeed, IIRF considers value creation only from the perspective of capital enhancement spurred by academic activities, overlooking the fulfillment of institutional missions as the true lever of value creation. This paper introduces a case study aimed at implementing IIRF at a University in Indonesia. The research is based on theory building from the case, action research, and intervention approaches. IIRF was chosen for its claimed ability to support communication processes with stakeholders and control over value creation, despite demonstrating some weaknesses. It highlights the role played by intellectual capital in the business model of organizations and in the value creation process. This adjustment appears to increase awareness of the role of intellectual capital in value creation at universities. In this paper, not one part of the adapted framework is innovative on its own, but collectively they provide an innovative solution, addressing the disclosure and managerial needs of the studied organization. The single case study allows us to test the claimed weaknesses of IIRF in the literature, suggest some adjustments to the original framework, and validate its effectiveness. Thanks to the single case study, we were then able to construct a theoretical framework that develops theory inductively; now the suggested framework can be tested and further validated in other organizations. This paper introduces an innovative approach to reporting and disclosing intellectual capital in universities. It is relevant not only for external communication but also for internal purposes, aiding managers in decision-making and actions.

Demineralisasi merupakan proses penghilangan ion-ion yang terkandung di di dalam air dengan adanya pertukaran ion menggunakan resin anion dan kation. Resin anion dan kation di dalam Mixed Bed akan menyerap ion-ion dalam air, namun seiring berjalannya waktu resin akan mengalami kejenuhan sehingga harus dilakukan proses Regenerasi. Regenerasi resin penukar kation dilakukan dengan menggunakan larutan H2SO4 dan regenerasi untuk resin penukar anion dengan menggunakan larutan NaOH. Regenerasi dilakukan dengan beberapa tahapan, setiap tahapan memiliki preset-time yang berbeda. Preset-time dapat berubah sesuai kondisi Mixed Bed pada saat dioperasikan. Penelitian dilakukan dengan tujuan untuk mengetahui pengaruh perubahan waktu pada tahap rinsing proses demineralisasi Mixed Bed terhadap nilai konduktivitas pada produk keluaran Mixed Bed sekaligus mengetahui jumlah penggunaan air demin secara efisien dalam proses regenerasi Mixed Bed pada tahap rinsing. Beberapa pertimbangan terhadap permasalahan pada saat regenerasi akan berpengaruh terhadap adanya perubahan preset-time. Penelitian ini dilakukan dengan melakukan perubahan waktu pada proses regenerasi di unit demineralisasi Water Treatment Plant Unit 7,8 PT. POMI. Pada penelitian ini dilakukan perubahan preset-time pada tahap rinsing dari 120 menit menjadi 60 menit. Hasil penelitian menunjukkan bahwa pengurangan waktu pada tahap rinsing selama 60 menit sudah memenuhi parameter konduktivitas <200 µS/cm yakni 90-110 µS/cm. Sehingga dengan adanya pengurangan waktu pada tahap rinsing akan berpengaruh pada penurunan jumlah penggunaan air demineralisasi untuk proses pembilasan resin dengan efisiensi sebesar 50% dan pengehematan pengeluaran biaya air demin sebesar ± Rp75.000.000 dalam satu kali proses regenerasi Mixed Bed.

Antimicrobial resistance is a global healthcare threat with significant clinical and economic consequences peaking at secondary and tertiary care hospitals where multidrug-resistant Gram-negative bacteria (MDR GNB) lead to poor outcomes. A prospective study was conducted between January and December 2019 for all invasive bloodstream infections (BSIs) secondary to MDR GNB in Qatar identified during routine microbiological service to examine their clinical, microbiological, and genomic characteristics. Out of 3238 episodes of GNB BSIs, the prevalence of MDR GNB was 13% (429/3238). The predominant MDR pathogens were Escherichia coli (62.7%), Klebsiella pneumoniae (20.4%), Salmonella species (6.6%), and Pseudomonas aeruginosa (5.3%), while out of 245 clinically evaluated patients, the majority were adult males, with the elderly constituting almost one-third of the cohort and with highest observed risk for prolonged hospital stays. The risk factors identified included multiple comorbidities, recent healthcare contact, previous antimicrobial therapy, and admission to critical care. The in-hospital mortality rate was recorded at 25.7%, associated with multiple comorbidities, admission to critical care, and the acquisition of MDR Pseudomonas aeruginosa. Resistant pathogens demonstrated high levels of antimicrobial resistance but noticeable susceptibility to amikacin and carbapenems. Genomic analysis revealed that Escherichia coli ST131 and Salmonella enterica ST1 were the predominant clones not observed with other pathogens.

Published: March 2024

The dinoflagellate Noctiluca scintillans is a globally distributed bloom-forming species. Previous studies have shown that the primary reason for the frequent occurrence of N. scintillans blooms may be the proliferation of microalgae due to eutrophication, which provides a sufficient source of food. Meanwhile, N. scintillans may release nutrients into the environment, thus affecting the population dynamics of microalgae. Thus, to investigate the interaction between N. scintillans and co-occurring microalgae, this study examined the population dynamics of N. scintillans and their interaction with three representative microalgae species in response to varying nutrient levels. The findings indicate that the growth of N. scintillans is slow when co-cultured with diatom Skeletonema costatum. Moreover, a high density and rapid growth rate of S. costatum may have an inhibitory effect on the growth of N. scintillans. Conversely, the population abundance of N. scintillans increased with the rise in the population density and nutritional level of Heterocapsa steinii (dinoflagellate) and Heterosigma akashiwo (raphidophyceae). Notably, N. scintillans can discharge specific nutrients into the aquatic environment, which can subsequently be assimilated and exploited by H. steinii. Thus, the interaction between the species and population dynamics of plankton, as well as changes in nutrient levels within the ecosystem, played a significant role in influencing the growth and population dynamics of N. scintillans. The mutualistic association between N. scintillans and microalgae may establish a transient closed loop, thereby fostering the sustained proliferation and subsequent expansion of N. scintillans.

Competition among trees for limited resources (e.g., sunlight, water, and nutrients) impacts their growth differently. Crown plays a crucial role in resource access for trees. However, uncertainties persist regarding crown size differences, tree growth, and tree competition levels between coniferous and broadleaf trees in mixed-age forests. We conducted a study on 3008 live trees across 28 plots in Hunan Province to measure individual crown size and tree growth increment. Introducing a new metric, the Crown Size Competition Index (CSCI), we assessed competition pressure among coniferous and broadleaf species in mixed-age forests. We examined the correlation between competition indices and tree growth increment while also investigating the influence of neighboring species diversity on tree competition. Our results revealed a significant negative correlation between the tree growth of Cunninghamia lanceolata (Lamb.) Hook.(CL) and Phoebe bournei (Hemsl.) Yang (PB) and the competition index. Increased competitive pressure on the focal tree corresponded to a decline in the growth of focal tree volume, with a more pronounced impact observed in PB compared to CL. The diversity of neighboring species contributed to variations in competition for the focal tree, with broadleaved species (PB) exerting a greater influence on the focal tree than coniferous species (CL). These findings underscore the competitive potential of PB in mature coniferous stands and advocate for the restoration of stratified mixes in CL broadleaf forests. Furthermore, our findings support the management strategies for the valuable tree species PB.

The objective of this study was to assess the impact of concentrated cottonseed protein (CPC) as a substitute for fishmeal (FM) in juvenile hybrid culter (Erythroculter ilishaeformis ♀ × Ancherythroculter nigrocauda ♂). A total of 360 fish with an initial body weight of 10.0 ± 0.5 g were randomly allocated into 12 indoor culture tanks, with each tank containing 30 fish. Four diets were formulated in which fish meal (FM) was replaced by CPC at different inclusion levels: 0% (T0), 15% (T15), 30% (T30), and 45% (T45). The corresponding amounts of CPC included were 0, 61, 122, and 182 g/kg, respectively. At the end of the 10-week feeding trial, the findings revealed an inverse correlation between the proportion of CPC replacing FM and both final body weight (FBW) and weight growth rate (WG) in hybrid culter. Specifically, the T30 and T45 groups exhibited significantly lower FBW and WG compared to the T0 group (p < 0.05). No significant differences in crude protein and ash contents were observed among all groups (p > 0.05). However, the crude lipid content was highest in hybrid culter fed the T45 diet and lowest in the T0 group (p < 0.05). There were no significant differences in muscle amino acid composition among all treatment groups (p > 0.05). The contents of total protein (TP) and albumin (ALB) declined slightly as the proportion of FM substituted by CPC increased, yet this decline did not reach statistical significance (p > 0.05). Serum alanine aminotransferase (ALT) activity elevated with increasing dietary CPC, and the T45 group exhibited significantly higher ALT activity compared to the T0 group (p < 0.05). The hepatic activities of superoxide dismutase (SOD) and catalase (CAT) were significantly lower in the T45 group than in the T0 and T15 groups (p < 0.05). Furthermore, there was a decrease in intestinal villi length with an increasing replacement ratio of FM by CPC, and the villi length in the T45 group exhibited a significant reduction when compared to that in the T0 group (p < 0.05). It is concluded that replacing 15% FM with CPC does not exert obviously detrimental effects on growth performance, serum biochemical indices, intestinal morphology, muscle amino acid profile, or antioxidant performance of juvenile hybrid culter.

In view of climate change and the increasingly antagonistic wine market, the exploitation of native genetic resources is revisited in relation to sustainable wine production. ‘Sideritis’ is a late-ripening Greek grape variety, which is quite promising for counteracting wine quality issues associated with the annual temperature rise. The aim of this study was to improve the quality and to enhance the aroma of ‘Sideritis’ wine through the use of native yeasts. To improve vinification, Hanseniaspora opuntiae L1 was used along with Saccharomyces cerevisiae W7 in mixed fermentations (SQ). The addition of H. οpuntiae significantly altered the chemical profile of the wine compared to the single-inoculated fermentations with W7 (IS). H. opuntiae increased all the acetate esters, except for hexyl acetate and (Z)-3-hexen-1-ol acetate. The concentration of 2-phenylethyl acetate, which imparts flowery and sweet notes, exhibited a 2.6-fold increase in SQ as compared to IS wines. SQ also showed higher levels in several ethyl esters, including ethyl butyrate, ethyl heptanoate and ethyl 7-octenoate, which are associated with fruity notes compared to IS. H. opuntiae produced citronellol, a terpene associated with rose and green notes, and increased the overall acceptance of the wine. Present results are thus quite promising for improving ‘Sideritis’ wine quality towards a sustainable wine production in Greece in view of global warming.

Complete mitochondrial genomes (mitogenomes) can provide important information regarding the molecular evolution and phylogenetic relationships of marine invertebrates, especially in Brachyura. Only one Cancroidea species of mitogenomes has been sequenced before; in this research, the mitogenomic characteristics of Metacarcinus magister (Cancridae: Cancroidea) are newly studied. The length of the M. magister mitogenome was 48,820 bp, and it contained the typical 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. We performed a series of analyses on the characteristics of the mNCR of M. magister. The phylogenetics, life circumstances, and selective pressures were all analyzed to explain the formation of this length, which revealed the length of the M. magister mitogenome to be approximately three times greater than the normal length of Brachyuran mitogenomes. Phylogenetic analyses based on a dataset of 215 Decapodan mitogenomes indicated that all Eriphioidea crabs were clustered together as a group. Moreover, the rearrangement mechanism of the Cancroidea species was predicted to provide stronger evidence for the phylogenetic analysis. In general, the results obtained in this study will contribute to a better understanding of the cause of the unusual length of the M. magister mitogenome and provide new insights into the phylogeny of Brachyura.
