Economic analysis of winter vegetable markets in Tunisia
Authors:   , Omezzine Abdallah
Published: May 2024

The rapid development of the non-traditional winter vegetable industry in Tunisia has resulted frequently in domestic market saturation and depressed prices. Frequent complaints suggest that the existing pricing system has served poorly in guiding the quantity, quality, and kind of production as well as the distribution of the product in form, space and time. The overall objective of this study is to develop market information essential for guiding public and individual production and marketing decision makers in this industry. The first task of the study was to analyze the working of winter vegetable markets in Tunisia and evaluate their performance. The second task was to analyze price and quantity movements over time of some selected winter vegetables and to explain the relationship between prices and the level of supply and demand for winter tomatoes. The analysis of market structure and conduct has found that the industry is still entirely oriented toward the internal market. The few vegetable exports have not generally emerged as the result of either systematic analysis of the market opportunities by producers and a deliberate long-term export plan, or a correspondingly careful evaluation of the production and marketing resources. Wholesale markets have been the largest outlet for these crops and market exchange has been the most important mechanism of vertical coordination between various units of this industry. Competitive behavior has prevailed at all stages of the various marketing channels. Performance analysis found evidence of efficiency in the existing scale and methods of operation of the various firms. However, spatial price data suggested that prices in major markets are not linked precisely by transfer costs. Intermarket arbitage cannot be made instantaneously because of conditions related to the specific structure and conduct of these markets, to the type of trade arrangements, and to the nature of the products. The analysis of price movements over time showed that prices have fluctuated sharply between one month and another and between successive years reflecting substantial changes in supply and demand conditions. The supply and demand analysis for winter tomatoes established demand relationships that linked per capita consumption of tomatoes to its own price, to per capita income and to the month of the year. The procedure also showed convincing evidence that supply response for tomatoes is a function of expected price ratio of cucumber over tomato prices. Vegetable growers were found to react not to last year's prices but rather to the price they expect and this expected price depends only to a certain extent on the level of last year's prices.
Growth regulation and mitogen binding in established rat ovarian cell lines
Authors:   , Turner John Thomas
Published: May 2024

Factors capable of supplanting serum in the growth stimulation of established rat ovarian cells in serum-free medium were determined. Among the potential mitogens tested, the most potent combinations consisted of low concentrations of epidermal growth factor (EGF) and transferrin (TFN) for the metastatic cell line OV1N and the same two proteins plus insulin (INS) and ovarian growth factor (OGF) for the steroidogenic, non-metastasizing cell line 31A- F2. These combinations produce proliterative responses equal to the mitogenically optimum serum concentration for the respective cell lines. The use of serum-free culture conditions has allowed the precise examination of the independent and synergistic roles played by various potential growth factors. EGF alone stimulates both cell lines. INS alone stimulates growth of 31A-F2 cells. These two polypeptides are thus considered growth factors. TFN, on the other hand, is not effective in stimulating growth when added alone but quite markedly enhances EGF's and INS's proliferative capacity. TFN is a growth co-factor. OGF is a survival factor for 31A-F2 cells. The effects on the basic mitogenic activity of these four compounds by other compounds that are generally active in membrane related events were also investigated. The initial interactions of the growth factor, EGF, and the growth co-factor, TFN, with the target ovarian cells were also studied. The iodo-derivatives of both factors bind to distinct membrane receptors of cells of both lines. The binding is of high affinity and limited capacity (saturable), time and temperature dependent, specific, and regulated by enzymatic treatment and the presence of other compounds. A correlation between the binding parameters (dissociation constant. Kg, and the number of sites per cell, Bmax) and the optimum concentration range required to elicit a biological response in each case is observed. The utility of the present system for future studies of not only growth regulation but also the regulation of unique cellular functions such as steroidogenesis is discussed.

IUCN Red List of Ecosystems, Mangroves of the South Kuroshio
Authors: Inoue Tomomi , Baba Shigeyuki , Akaji Yasuaki , Miura Shingo , Oshiro Nozomi , Kezuka Mio , Suarez Ena
Published: May 2024

Mangroves of the South Kuroshio is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of the Central Kuroshio Current and South Kuroshio. In 2020, the mapped extent of the South Kuroshio mangrove province was 8.0 km2, representing less than 0.01% of the global mangrove area; the biota is characterized by 19 true mangrove species. Mangroves in this province are now well conserved, and their distribution is tending to expand through natural processes. Because this province is close to the northern limit of mangrove distribution, mangrove flora and fauna are adapted to low temperatures and distinct seasonality. Many of the effects of climate warming on the organisms living among mangroves remain unclear and need to be monitored. In 2020, the South Kuroshio mangroves cover 43% more area than our estimate for 1970. Since 1996, there has been a net increase in mangrove area of 0.39%. Although this trend might continue linearly over the next 50 years, in reality, the mangrove area should plateau when the maximum potential growth area of mangroves is reached. In contrast, spatially isolated and small-scale mangrove ecosystems are vulnerable in the event of a severe disruption impacting a wide area. Under a high sea-level rise scenario (IPCC RCP8.5) ≈8.2% of the South Kuroshio mangroves would be submerged by 2060. Moreover, 0.43% of the province’s mangrove ecosystem is undergoing degradation, with the potential to increase to 1.26% within a 50-year period, based on a vegetation index decay analysis. Overall, the South Kuroshio mangrove ecosystem is assessed as Least Concern (LC).

Mangroves of the Warm Temperate Northeast Pacific is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of the South-Californian Pacific and the Gulf of California. The mapped extent of the Warm Temperate Northeast Pacific mangrove province in 2020 was 1,810.4 km², which represents 1.5% of the global mangrove area. There are three species of true mangroves that characterize the biota: Rhizophora mangle, Laguncularia racemosa and Avicennia germinans. These mangroves all grow on a southeast-northwest latitudinal axis, from greater to lesser structural complexity due to less favourable temperature conditions and availability of freshwater with increasing distance from the tropical zone. The main threats to the mangrove ecosystem in this region derive from changes in hydrological and sediment regimes, almost always related to the development of local infrastructure, such as canals and roads or the construction of upstream dams. Another emerging threat is the increased incidence of hurricanes in the region, which have affected large areas mainly in the last five years. Based on our analysis, it has been estimated that the Warm Temperate Northeast Pacific mangroves have expanded their coverage by 12.46 % since 1970. Nevertheless, the net area change has been -8.5 %. If this trend persists, it is anticipated that there will be 8.2 % reduction in coverage to 2055. Based on the IPCC RCP8.5 high sea-level rise scenario, it is estimated that the Warm Temperate Northeast Pacific mangroves will experience significant submergence of approximately 26.6 %, by the year 2060. Additionally, ~3 % of the mangrove ecosystem in the province is undergoing degradation currently, and this percentage is expected to increase to 8.7 % within the next 50 years. These estimated are based on a vegetation index decay analysis. The Warm Temperate Northeast Pacific mangrove ecosystem is currently assessed as Near Threatened (NT).
Morphometry of the Citrus Mealybug Planococcus citri (Risso) and its Feeding Impact on the Proximate Composition of Citrus Species Leaves in Makurdi Southern Guinea Savanna, Nigeria
Authors: Iyongo Terungwa T. , Ukwela Monday
Published: May 2024

The study assessed the feeding impact of citrus mealybug Planococcus citri (Risso) and its morphometry on (Citrus species L.) at the Teaching and Research Farm, Joseph Sarwuan Tarka University, Makurdi.  A 2x5 factorial experiment comprising five species of two-year-old citrus seedlings (C. sinensis, C. nobilis, C. reticulata, C. limon, and C. aurantium) each replicated three times were planted on the field under screen cages in a Randomized Complete Block Design (RCBD). Fifteen stands were infested with 20 young adult female mealybugs each while 15 were un-infested to serve as the control. Data collected was analysed using GenStat Release 2007 (7.2) and means were separated by Duncan’s Multiple Range Test (DMRT) at P = 0.05. Results showed that the percentage of dry matter content was highest on the control compared with the infested plants. The proximate content of the host plant leaves indicated that all the control plants had more sugar than infested plants. Crude fibre and Ash content of infested host plants were lower than that of un-infested.  The impact of mealybug feeding was most pronounced on C. sinensis and C. reticulata. Morphometrically, males of P. citri found on C. nobilis were in body length, width, and weight.  Adult females, however, showed no significant variation in length and width across all citrus species. C. aurantium produced the heaviest females while C. reticulata had females with the lowest weight. In conclusion, C. nobilis is suitable for commercial production of seedlings. Routine inspection for early detection of mealybug infestation is recommended.
Association of endothelial nitric oxyde synthase (eNOS) levels and modifiable risk factors for acute myocardial infarction with ST-segment elevation (AMI-STE)
Authors: Leona Denada Florencia , Syafri Masrul
Published: May 2024

Background. The pathological process underlying myocardial infarction is atherosclerotic thrombosis that causes endothelial dysfunction. In the AMI-STE process, eNOS has functions as the body's defense mechanism to prevent more severe damage to the endothelium. Decreased eNOS levels were found in modifiable AMI risk factors. This study aimed to determine the association of eNOS levels based on modifiable risk factors for AMI-STE patients.
Method. This study was an analytical observational study with a historical cohort design. The samples were patients with AMI-STE diagnosis who had undergone PPCI at M. Djamil Hospital Padang from March to June 2022. The eNOS levels were taken from the blood samples. Modifiable AMI risk factors were taken from patient’s medical record. The T test was carried out to determine statistical analysis.
Results. The average age of the 38 subjects was 62.53 ± 8.2 years, and 92.1% among them were male, and 52.6% subjects were diagnosed with anterior AMI-STE. The average eNOS level in subjects was 47.47 ± 23.88 (normal level is 48.16 pg/mL). More than half (73.5%) of the subjects in low eNOS group had diabetes mellitus as risk factor (P<0.0001) and most subjects (78.9%) in group with low eNOS had hypertension (p=0.022). Other risk factors, namely dyslipidemia and smoking, were also more common in group with low eNOS. However, statistical tests showed that there was no statistically association between eNOS levels with dyslipidemia and smoking.
Conclusion. There was statistically significant association between eNOS levels with diabetes mellitus and hypertension as modifiable risk factors for AMI-STE.

INTRODUCTION. Environmental deterioration is a matter of great concern caused in part by industrial activities, where the main impacts are generated through emissions, solid waste and polluting wastewater. OBJECTIVE. To analyze the generation and treatment of wastewater resulting from industrial operations in terms of current expenditure and investment made by manufacturing industries in Ecuador. METHOD. The numerical data are cross-sectional, for which three levels of research were covered: descriptive, correlational and explanatory. The database of the environmental economic information module in companies (ENESEM) of the year 2020 was used. RESULTS. 53.2% of Ecuadorian manufacturing industries allocated resources in current expenditures to prevent surface water pollution by reducing the release of wastewater (including wastewater collection and treatment) and only 4.5% allocated resources in investment for the treatment of this water. DISCUSSION AND CONCLUSIONS. The activities that presented the highest level of correlation with current expenditure were wastewater treated, wastewater generated and the amount of water captured from natural sources. In this sense, manufacturing companies should focus their efforts on issues related to the generation and treatment of wastewater from their productive activities.

A Review of Novel Medical Treatments for Thyroid Eye Disease
Authors: Park Jeong Woo , Yoon Jin Sook
Published: May 2024

Thyroid eye disease (TED) is the most common extrathyroidal manifestation of Graves disease. There has been no effective medication to prevent proptosis in thyroid eye disease until 2020 when the anti–insulin-like growth factor 1 receptor (anti–IGF-1R) antibody, Teprotumumab, was approved by the US Food and Drug Administration, sparking increased interest in immune-based drug development. This study aims to review the newly developed drug therapy as well as conventional treatment for TED. Treatment of TED has traditionally been high-dose steroids and orbital radiotherapy, but recently there has been a paradigm shift in the treatment of TED in the United States with the introduction of the therapeutic agent teprotumumab, which dramatically reduces proptosis. However, concerns remain about the development of hearing impairment as a potentially fatal complication and long-term safety. Recently, several clinical trials are underway to assess the efficacy and safety of novel drugs targeting mammalian target of rapamycin complex 1, interleukin-6, fragment crystallizable receptor, and IGF-1R in treating TED. With the explosive increase in interest from academia and pharmaceutical companies in TED, there is anticipation for the development of drugs that are equivalent or superior to teprotumumab while being safer.

There is no traffic-related education in the general educational curriculum of Saudi Arabia, and teenagers can acquire a licence without receiving traffic education. Consequently, the lack of sufficient traffic education can be a contributing factor to road traffic crashes (RTCs). This quantitative research study implemented a Structured Traffic Education Program (STEP) among 270 male students, all 18 years old. The study assessed demographic and driving experience characteristics and their association with exposure to car crashes and traffic violations. It is also an intervention study where there is statistical testing between baseline and follow-up data collection mediated by an intervention education program. It also analysed the levels of knowledge and self-reported commitment to traffic rules related to risky driving behaviours (RDBs) before and after implementing STEP. It was found that 66.3 percent of participants started driving at an illegal age, and only 1.5 percent underwent traffic education at a related institution. In addition, 67.8 percent of participants were unlicensed, 45.9 percent received at least one traffic violation, 34.1 percent were the mistaken party (at-fault driver) in crashes, and 56 percent watched drifting scenes out of curiosity or desire to be involved. Using a mobile phone while driving was the most prevalent RDB (77.8%). Saudis, drivers who started driving at an illegal age, car owners, and major traffic violators were significantly associated with causing crashes as the mistaken party (at-fault driver). The STEP program improved knowledge, commitment to traffic rules, and patterns related to RDBs. Additionally, driving licences should not be granted without comprehensive traffic education at driving schools. This study aims to contribute to reducing the epidemic of road traffic injuries (RTIs) and emphasises the importance of incorporating traffic education into school curricula.
Crowdsourcing User-Centered Teams
Authors:   , Vinella Federica Lucia
Published: May 2024

Crowdsourcing has become an increasingly important tool for team formation and collaboration. This thesis investigates how User-Centered Design, an iterative process that prioritizes users and their needs, can be applied to improve the efficiency and effectiveness of crowdsourcing systems for teamwork and team formation. To achieve this, we conducted a series of studies to explore the role of various factors in shaping crowd workers' behaviour and preferences in collaborative contexts.

The main findings of our research are as follows.
In online team formation settings, crowd workers prefer disclosing overt traits (e.g., age, gender, topical interests) and avoid sharing sensitive information (e.g., ethnicity, depression). However, they are willing to share information regarding their personality and values, typically considered deep-level sensitive traits.
Well-defined digital nudging interventions, such as a diversity progress bar, can promote diverse team formation. In contrast, subtler forms of nudging may inadvertently trigger biases working against the intended objectives.

Ad-hoc crowd teams working under pressure can benefit from systems that account for differences in personality traits, as these can influence collaboration outcomes and perceptions. Designing crowdsourcing systems for emergency response requires modelling communication tools that aid, assist, and monitor the shared load, considering the strictly cooperative roles and task- and user-dependent communication styles between collaborators. When forming teams, crowd workers tend to balance attributes between and within groups, with a preference for Openness to Experience among the Big-5 personality traits.

Based on these findings, we recommend applying a User-Centered approach to design collaborative crowdsourcing systems, considering user needs, behaviour, intents, and perceptions of digital environments. Future research should continue to explore and evaluate innovative strategies for promoting effective collaboration and team formation in crowdsourcing contexts.
