Potential Confusion Between Value Investing and Fundamental Analysis Explored Through Piotroski F-Score
Authors: Murti Nugroho Wisnu , Sugiri Slamet 
Published: February 2025

This article addresses the potential confusion between fundamental analysis (FA) and value investing (VI) in stock analysis, particularly highlighting the over-reliance on financial ratios that can obscure their distinctions. It examines the role of the f-score, developed by Piotroski (2000) as a VI indicator, which is frequently misinterpreted within the context of FA. By analyzing its utilization in academic literature, the study examines to clarify how the f-score should be understood as a value investing tool and contribute to a clearer framework distinguishing the two approaches, thereby enhancing future research and educational efforts. This article employs bibliometric analysis. Our study finds that while the f-score is frequently associated with FA metrics, its intended purpose as a measure of VI more relevant. Additionally, we categorize value investing indicators into Single Value Investing Indicators (SVII) and Combined Value Investing Indicators (CVII), building upon the foundational works of Graham & Dodd (1934) and Lakonishok et al (1994). The findings suggest that Piotroski's f-score is more appropriately classified as a CVII and more effective in predicting abnormal returns when used within the value investing framework rather than fundamental analysis.
How endocrine disruptors affect fish reproduction on multiple levels: A review
Authors: Socha Magdalena , Chyb Jarosław , Suder Aleksandra , Bojarski Bartosz 
Published: February 2025

Abstract
This review paper presents fish reproductive toxicology studies with a specific focus on endocrine-disrupting chemicals (EDCs) present in the aquatic environment. These substances, including bisphenols, heavy metals, pesticides, phthalates, and polychlorinated biphenyls (PCBs), act as hormone mimics, receptor blockers, or enzyme inhibitors that affect hormonal regulation in the hypothalamic-pituitary-gonadal (HPG) axis. In this review, we provide an overview of the adverse effects of these pollutants on both female and male fish reproduction (i.e., hormonal disruption in the HPG axis, gametogenesis disorders, disturbed embryogenesis, etc.). Even at low concentrations, EDCs can exhibit reproductive toxicity in fishes. They can affect the functioning of certain systems within the hypothalamus (Kiss/GPR54, GnRH) and can also impact luteinizing hormone (LH) secretion in the pituitary. These compounds have negative impacts on gonads, oocyte maturation, steroidogenesis, and gametes. Early-life exposure to these substances not only affects embryonic development, resulting in increased mortality and body malformations, but this also induces genetic changes in newly hatched larvae. All these observations underscore the need for monitoring the aquatic environment for EDCs and implementing protective measures to preserve the health and welfare of fishes and safeguard water ecosystems.

Abstract
The emergence of diseases and the indiscriminate use of antibiotics have had deleterious consequences in the aquaculture industry. Consequently, the growing emphasis on eco-friendly alternatives has taken center stage, and probiotics have emerged as a notable solution. This investigation aimed to identify and characterize potential probiotic bacteria present in the gills and intestine of rainbow trout (Oncorhynchus mykiss (Walbaum)). A total of 29 isolates were selected for in vitro evaluation. The assays included morphological evaluation, catalase, oxidase, hemolysis, pathogen antagonism, antimicrobial susceptibility, protease, and amylase tests. Seven isolates exhibited antagonism against one of the three pathogens tested (Aeromonas hydrophila, Streptococcus agalactiae, and Lactococcus garvieae). None of the isolates showed resistance to the antibiotics ampicillin, florfenicol, or tetracycline. Furthermore, all isolates showed proteolytic but not amylolytic activity. The isolates with the best characteristics were identified as Lactococcus lactis (n=7) by 16S rRNA gene sequencing.
An investigation on the population parameters of freshwater crayfish (Pontastacus leptodactylus Eschscholtz, 1823) in Lake Yeniçağa (Bolu)

Published: February 2025

Abstract
This study examines the monthly population parameters of Pontastacus leptodactylus in Lake Yeniçağa, including sex, length, and weight compositions, length-weight relationship, fecundity, morphometry, meat yield, and crayfish plague ratio. For this purpose, 641 crayfish were collected using fyke nets with a 34 mm mesh size. The females carrying eggs were observed between February and May. The female specimens carried between 103 and 841 eggs each, with a diameter ranging from 2.03 to 2.82 mm. The research revealed a size range of 80–168 mm and weight range of 15–133 g for crayfish specimens. As a result of regression analyses, the length-weight relationship was calculated as W = 0.0392L2.9148 for males and W = 0.0701L2.6139 for females. The population exhibited negative allometric growth based on the length and weight data. The evaluation of meat yield was based on the total meat yield, which comprises cheliped meat yield and abdomen meat yield. The study found that 14.35% of the P. leptodactylus population in Yeniçağa Lake was affected by crayfish disease. The results indicate that the P. leptodactylus population in Lake Yeniçağa has an overall healthy population structure, with a size suitable for fishing, and should be considered from an economic standpoint.
The first data from non-commercial monitoring of the occurrence and range of river lamprey, Lampetra fluviatilis, in selected rivers in northern Poland
Authors: Kuczyński Tomasz 
Published: February 2025

Abstract
Human impact on fish populations extends beyond mere exploitation. Rivers and streams, essential conduits for these fish migrations, have undergone substantial anthropogenic modifications driven by navigation, hydropower generation, and water regulation imperatives. An example of one species that has been affected from the anadromous lampreys is river lamprey, Lampetra fluviatilis (L.). Populations of anadromous lampreys have declined dramatically in European rivers, including in Poland, because of the loss of river connectivity and habitat modification that prevents adult lamprey from reaching their original spawning grounds. The present study was conducted on 11 rivers located in northern Poland in the southern Baltic Sea catchment area. River lamprey spawners were sampled with dedicated traps, and 3,026 specimens of 29 fish species were caught at all the sites investigated. The most abundant, frequent species was river lamprey (n = 1,062), which was recorded in 10 of 11 rivers. Only in one case, were river lamprey specimens recorded above a barrage with a fish pass in a tributary of the Rega River. In all other rivers, lamprey was recorded only at sampling sites below the first barrier. Since most fish passes are not designed to provide passage for weaker swimming or non-jumping species, they are not suitable for non-salmonid species like river lamprey.

Abstract

Trichiurus lepturus is a benthopelagic species of socio-economic importance in Senegal. Despite its intensive exploitation, there is a lack of studies on its life traits in West African waters, particularly in Senegal. This study aims to determine the biological parameters of this species in the northern coastal zone of Senegal. Samples were collected monthly from April 2015 to March 2016 in Cayar, one of the main landing sites in Senegal. A total of 354 specimens were caught with longlines. Condition factor varied between the years with a peak in May. Positive allometric growth (b = 3.24) was found for this species. The reproductive period mainly occurred from April to July, and the sizes at first sexual maturity were 831 mm and 766 mm for females and males, respectively. Absolute fecundity was highly variable (39,976.88 ± 19,793.02 oocytes). The growth parameters estimated were asymptotic length (L∞) = 134 cm and the growth coefficient (K) = 0.0016. The maximum observed age was 1 year and 7 months. These parameters could be integrated into stock assessment models, providing a better estimate of the exploitation level of this resource and aiding in the formulation of more scientifically informed management measures for sustainable exploitation.
Effects of preserving juvenile rainbow trout (Oncorhynchus mykiss) in formalin and alcohol on body length, mass, and condition factor estimates
Authors: Greszkiewicz Martyna , Fey Dariusz P. 
Published: February 2025

Abstract
Body length and weight are key parameters measured to provide information about the growth and condition of larval, juvenile, and adult fishes from both the wild and aquaculture. The goal of this study was to evaluate the effects of preservation in formalin and alcohol on juvenile rainbow trout, Oncorhynchus mykiss (Walbaum) standard body length (SL) and weight changes. Standard length (19.43–32.98 mm SL) decreased after 60 days of preservation by an average of 2.98% in 96% alcohol and 2.26% in 10% formalin. In contrast, fish body weight (0.094–0.63 g) decreased in alcohol (31.22%) but increased in formalin (11.65%). These percentage values can be used as correction factors, with the exception of fish body weight in alcohol since the size of individuals affected the magnitude of change. Accordingly, a correction formula accounting for fish weight must be applied (fresh weight (g) = -0.0363 + 1.667 × preserved length). Changes in fish length and body weight in different preservatives resulted in significant differences in the Fulton condition factor, with underestimation in alcohol (fresh F = 1.58; preserved F = 1.20) and overestimation in formalin (fresh F = 1.60; preserved F = 1.92).
Historical occurrence of Atlantic sturgeon, Acipenser oxyrinchus Mitchill, 1815, in the tributaries of the Vistula River in Poland
Authors: Cios Stanisław 
Published: February 2025

Abstract
All known historical accounts of the occurrence of Atlantic sturgeon (Acipenser oxyrinchus Mitchill) in the tributaries of the Vistula River are presented and analyzed. Sturgeon occurred in most large, medium, and small Vistula tributaries and in the upper reaches of the Vistula River in Silesia. The fish either migrated or strayed there rarely and irregularly, usually as single specimens and mainly during high waters. The data available do not provide evidence that sturgeon spawned successfully in any of the tributaries. In particular, the data do not support the commonly held view that Drwęca was the most important spawning river after 1918, which is the basis of the ongoing sturgeon reintroduction program.

Abstract
Microalgae have emerged as a promising feed supplement in aquaculture diets. Therefore, the aim of this study was to investigate the effect of Chlorella ellipsoidea as a feed supplement on the growth performance, body composition, and hematology of stinging catfish, Heteropneustes fossilis (Bloch). Five experimental diets were formulated to conduct this experiment by supplementing 0, 2.5, 5.0, 7.5, and 10% C. ellipsoidea at the expense of fish meal, and these are referred to as the control, CE 2.5, CE 5, CE 7.5, and CE 10 diets, respectively. A total of 900 fish (mean body weight of 0.50 ± 0.01 g) were divided equally into15 glass aquaria (180 L). Triplicate groups of fish were fed with each experimental diet to satiation twice daily for 10 weeks. At the end of the feeding trial, the weight gain (%) of the fish fed CE 5 and CE 7.5 was significantly (P < 0.05) higher than that of fish fed the control diet. The specific growth rate (SGR) of the fish fed CE 5 was significantly higher (p < 0.05) but comparable to those fed CE 2.5 and CE 7.5. The feed conversion ratio (FCR) of the fish fed CE 5, CE 7.5, and CE 10 was significantly (P < 0.05) lower, and the protein efficiency ratio (PER) of the fish fed CE 7.5 and CE 10 was significantly (P < 0.05) higher compared to all the other diets. In comparison to the control, dietary C. ellipsoidea of 5.0–10.0% significantly (P < 0.05) increased the protein content of stinging catfish, while lowering the lipid and moisture contents. The red blood cells, white blood cells, hemoglobin, hematocrit, and mean corpuscular hemoglobin levels of H. fossilis increased significantly (P < 0.05) when the fish were fed 5.0–10.0% dietary C. ellipsoidea compared with the control. Based on the findings of the study, 5.0–10.0% C. ellipsoidea supplementation was optimal in the stinging catfish diet to improve growth performance, body composition, hematology, and immunological response. However, based on regression analysis, the optimum level of C. ellipsoidea as a feed supplement was calculated to be 4.9–5% in stinging catfish.

Underinsurance of Real Estate: A Threat to Policyholders and Insured Entities
Authors: Janáčková Hana , Přečková Lenka 
Published: February 2025

Abstract
The aim of the article is to demonstrate the risk of underinsurance in selected production halls used for business activities in the Czech Republic by means of a case study. The case study determines the insured value in the new price category for three selected production halls. New price is a specific term for property insurance in the Czech Republic and means the replacement value of the property. The cost method of valuation is used to calculate the new price. The insured value is determined by an insurance broker, and two brokerage companies were approached for this purpose. The replacement cost is determined by the independent property appraiser using the valuation decree applicable from 1 January 2024. The case study compares the calculated new prices, assesses their level in terms of the risk of underinsurance and then makes a suggestion of problem areas that should be addressed in the Czech Republic, as they put the policyholder at risk. The results of the case study show an asymmetry of information between the policyholder and insurer. This is due to unavailable or unclear, yet very important information for the policyholder. In order to reduce information asymmetry and the occurrence of underinsurance, it seems important that all insurers follow an explicit procedure leading to the determination of the insured value, which would be known to the policyholder prior to the conclusion of the insurance contract. It seems appropriate to use the current valuation decree, which has been updated annually in the Czech Republic for 35 years, for the procedure of determining the insured value.
A Contextual Analysis and Critical of e-Government as a Form of Public Accountability and Equitable Public Service Delivery

Published: February 2025

The purpose of this study is to critically analyze and contextualize the implementation of e-government in Situbondo Regency. E-government is adopted by the government with the belief that it can strengthen public accountability and enhance the distribution of public services. However, a significant portion of citizens remains unable to access e-government services. The research uses a contextual analysis approach combined with in-depth interviews to explore key ideas relevant to the analysis. The bureaucratic reform in the public policy system lacks humanistic values, diminishes the spirit of public service, and does not reflect good governance. E-government while seen as a technological revolution, faces the challenge of the digital divide, which silences citizens' rights due to a lack of digital literacy. As a result, public accountability is not effectively established through e-government.

Published: February 2025

This paper presents an experimental characterization of liquid nitrogen (LN2) thin-film evaporation on additively manufactured and Computer Numerical Control (CNC)-machined metal micropillar arrays. Five different additively manufactured and CNC-machined titanium (Ti-64) and stainless-steel (SS-304) micropillar surfaces with [Formula: see text] heating area were tested at a pressure of 1.38 MPa and a saturation temperature of 110 K. The micropillars had widths of [Formula: see text], [Formula: see text], and [Formula: see text] wall-to-wall spacing and [Formula: see text] height. An optimum micropillar spacing was observed where the heat flux was maximized to [Formula: see text] at approximately [Formula: see text] for the additively manufactured Ti-64 surface owing to the increased mean wicking velocity. A 44.5% decrease in dry-out heat flux was observed for the micropillar surface with the higher thermal conductivity material SS-304 compared to that with Ti-64, which can be attributed to the reduced bubble nucleation time and superheat. A 34% enhancement in dry-out heat flux was observed for the additively manufactured surface compared to the CNC-machined counterpart, which can be attributed to the augmented intrinsic surface roughness. A comparison of the experimental results with the literature model showed that the model overpredicts the dry-out heat flux limit of LN2 thin-film evaporation on both additively and conventionally manufactured metal surfaces.

Published: February 2025

Objectives:
Kirschner wires (K-wires) in orthopedic surgery have stood the test of time. They have several advantages and very few disadvantages. Being the most used and easily available implant, K-wires are very important in this specialty. Certain hand and wrist surgeries require specialized implants, which can be costly and not readily available in smaller hospitals and lesser developed nations. The authors want to discuss improvisation in the K-wire design in the form of (1) the introduction of crimping in the K-wire to cut them in flush with the cortex to avoid the infection associated with the unburied K-wire left outside the skin. (2) Incorporation of a hole in the above-mentioned crimped wire to make a modified suture anchor. (3) The threads at the tip and the shaft of the wire will make it useful in maintaining the released thumb web.

Methods:
Our study included 11 cases of crimped K-wires, eight cases with a hole (like a suture anchor), and five cases of threaded K-wires. Patients were followed up with radiographs, and a functional assessment was performed using mini disabilities of the arm, shoulder, and hand scoring.

Results:
All patients had good radiological and functional outcomes with no implant-related complications reported.

Conclusion:
K-wire modifications can be a game changer in small centers in developing countries. Our described modifications can be easily replicated, improving patient care by significantly reducing the cost of the treatment without compromising the final outcome.
