ABSTRACT. Ti(III) and (IV) hydrazide complexes were synthesized, characterized, and screened for their tyrosinase and lipoxygenase inhibitory and cytotoxic activities. The geometry of Ti(III) hydrazide complexes is tentatively assigned as octahedral. Magnetic moments were found around 1.7 B.M. and electronic spectral transition in the range of 495-518 nm. Evaluation of Ti(IV) and Ti(III) hydrazide complexes for tyrosinase and lipoxygenase inhibitory activities revealed varying inhibition potential. Hydrazide ligands were inactive against tyrosinase, while significant activity was observed against lipoxygenase (LOX). Good to moderate inhibition activity was observed by Ti(IV) and Ti(III) hydrazide complexes against both enzymes. At the same time, promising results were obtained for Ti(IV) hydrazide complexes against tyrosinase enzymes suggesting their broad application as tyrosinase inhibitors. Complex 4d possess negative inhibition, thus behaving as a tyrosinase activator. The docking results showed a good correlation between complex experimental activities and binding energies. Cytotoxic investigation revealed the non-toxicity of complexes against normal cells.

Plants are determinant of air quality and are useful in mitigating air pollution and biomonitoring of the pollution stresses.  Present study assessed the effect of stone-mining dust accumulation on foliar parameters and air pollution tolerance index (APTI) of five plants (Annona senegalensis, Bridelia ferruginea, Ficus capensis, Nauclea latifolia and Protea madiensis) commonly growing around an artisanal stone-mining site at Eziani Nsukka and Botanic Garden of the University of Nigeria, Nsukka, the control. Dust load was estimated gravimetrically. The foliar analysis carried out on the epidermises was obtained by clearing method and studied under microscope and all photomicrographs were taken with Moticam Camera 2.0 attached to the microscope. Biochemical parameters and APTI were determine following standard methods.   Dust accumulated on polluted plant leaves was high and resulted in distortion and deformation of the epidermal and guard cells. The cells appeared stretched and broken compared to the control plants. Quantitative stomatal indices such as length, width, size and density were also significantly affected by dust pollution. Polluted plants showed increase in ascorbic acid, reduction in pH values, relative water content and total chlorophyll content, and produced low tolerance index than the controls. Highest and lowest APTI were found in A. senegalensis and B. ferruginea. At polluted site, A. senegalensis had APTI (17.14 ± 0.24) and B. ferruginea had (11.38 ± 0.07) which differed significantly from the APTI of A. senegalensis (18.92 ± 0.24) and B. ferruginea (13.49 ±0.28) at the control site. A. senegalensis was the most tolerant to air pollution while other plants were intermediate tolerant plants. The abnormalities in artisanal stone-mining plants may be due to prolonged exposure to dust. However, ability of the plants to tolerate air pollution makes them potential good environmental cleaners and as such, are recommended as choice plants around stone-mining and dust-polluted sites for safer environments and better health of both miners and the inhabitants.

Published: December 2022

Fifteen weeks (105 days) feeding trial was conducted to determine growth response and economic benefit of replacing fishmeal with cattle hoof meal (CHM) in the diets of African catfish (Clarias gariepinus) juveniles. Five isonitrogenous diets containing 42% crude protein were formulated in which CHM replaced fishmeal at 0%, 25%, 50%, 75% and 100% (coded as D2, D3, D4, D5 and D6 respectively). A commercial feed (D1) was used as reference diet. Two hapa partitioned into six treatments of three replicates each embedded in a concrete pond of 5m by 3m by 2m was used for the experiment. The fish were fed at 3% body weight three times daily between the hour of 6.00 am and 7.00am, 2.00 pm and 3.00pm, and 10.00 pm and 11.00 pm. The feeding ration was adjusted every three weeks after weighing. The mean of the monitored physico chemical parameters of the water in the experimental tank were pH (7.12), temperature (28.25oC), oxygen (5.77mg/l), ammonia (0.04mg/l), nitrite (0.04mg/l), nitrate (0.03mg/l) and bicarbonate (5.45mg/l). The proximate composition of cattle hoofs meal were 33.75% moisture content, 66% dry matter, 58.06% crude protein, 2.75% crude fibre, 3.25% crude lipid, 0.91% ash content and 1.78% Nitrogen free extract. Feeding trials indicated that all fish consumed the experimental diets actively. Fish fed with the commercial feed had the highest mean weight gain (204g), followed by those fed with the experimental diet with 25% of CHM (D3) (181g). The fish fed with the control diet with no cattle hoofs meal (D2) had lower mean weight gain compared to the fish fed with 25% CHM. The fish fed with 50% CHM, 75% CHM and 100% CHM exhibited a decreasing weight gain (148.60g, 143.73g and 129.00g respectively) as the substitution level of the CHM meal increased. The fish fed with 25% cattle hoof meal (D3) had the best growth performance and feed utilization proficiency (specific growth rate 2.58, relative growth rate 1403, protein efficiency ratio 1.67 and feed conversion ratio 1.47) among the fish fed the formulated diets (D2, D3, D4, D5 and D6). There was no significant difference (p˃0.05) in the survival value of fish fed with all the experimental diets. The fish fed with D3 had the best net profit (₦46.53) followed by D6 (₦45.63), D1 (₦42.54), D5 (₦41.61), D4 (₦31.49) and D2 (₦20.59) in decreasing order. This study revealed that CHM can replace fishmeal at a lower cost and efficient diets for Clarias gariepinus. The best result was produced at the substitution level of 25% inclusion of CHM. It is recommended that CHM be included in the feed of Clarias gariepinus at 25% for optimum growth performance and reduced cost of production.

Published: December 2022

Safety of food is still a public health challenge globally. Fresh vegetables can be contaminated with pathogenic microorganisms from farm to table. This study evaluates the microbiological quality of ready to eat vegetables sold in Yankaba market, Kano. A total of forty (40) vegetables (cabbage, carrot, cucumber and lettuce) were collected from Yankaba Kasua and Kasua Turawa, and transported to the laboratory under aseptic condition to determine the bacterial load and fungal loads, identification of bacteria and fungi found in ready to eat vegetables using standard protocols. All samples collected had varying level of bacterial contamination ranging from 1.32x105CFU/ml to 1.45x106CFU/ml. The highest mean fungal count was observed in cabbage samples obtained from Yankaba Kasua (8.8x103MC/ml) and carrot from Kasua Turawa (8.0x103MC/ml) whereas the least fungal count was observed in lettuce sample obtained from Kasua Turawa (3.2x103MC/ml). Escherichia coli and Staphylococcus aureus were the predominant bacterial isolates accounting for 28.75% and 23.75% respectively whereas Shigella species and Enterobacter species were the least bacterial specie identified from this study, no Salmonella was isolated from this study. Aspergillus genera was found to be the most common fungi specie identified in all the samples accounting for 58.46% of the fungi identified and Geotrichum species was the least fungi identified. This study clearly shows ready to eat vegetables harboured high microbial load majorly E. coli, S. aureus and Aspergillus species which could pose a potential hazard to consumers. There is an urgent requirement for good microbiological practice in handling of ready to eat vegetables, hence the need for application of critical control point of washing in brine and vinegar during preparation.

Authors: Valdon Yunis Boga , Maigari Sadiq Abubakar
Published: December 2022

Upper Cretaceous sediments (Numanha and Lamja Formations) in the Yola basin of Northern Benue Trough have been investigated in order to characterize the particulate organic matter (POM) in the samples. The aim is to understand the rapid facies changes in both vertical and lateral direction of the formations and the relative abundance of the different organic components within the sections. The investigation involved 62 samples from four outcrop sections. The analysis involved series of laboratory procedure ranging from sample preparation, chemical treatment with HCl and HF, sieving, slide cover and completion then the counting of 300 particles per sample. The samples yielded sufficient organic residues for detailed palynofacies analysis. The organic constituents observed in the studied samples have been classified into phytoclast, palynomorp and amorphous organic matter groups. The phytoclast group predominates in almost all the sections followed by the palynomorp group with little amount of amorphous organic matter (AOM). The palynofacies parameters used for the study are the continental/ marine and opaque/translucent ratios which led to the construction of the sea-level variation pattern for the formations using Tilia 2.0.2 program.

The study examined at local level the role of cotton and textile industrial linkage in employment opportunities in the cotton value added chain in Funtua region of Katsina State. An interview and direct observation method of data collection methods were typically undertaken to learn about the cotton and industrial processes and how they give rise to their respective products and by-products. Seven (7) agro-based industries were identified and visited in their various locations in the study area were purposively selected. The study investigated the forward and backward linkages processes that the five (5) active cotton and textile industry agreed to. Results indicated that few cotton and textile industry had folded up but majority of them are operating at low capacity most especially Funtua textile Limited that is currently hit with high cost of production, poor raw material supply, erratic power supply and lack of government support. The study identified the existence of weakness in backward linkage of agriculture in the developing economy of the study area. Finally, the conclusion offers suggestions that the weakness in the backward linkage can be alleviated when local farmers are empowered, by introducing them into mechanized system of farming, providing them with farm inputs and market opportunities. This would amount to making the study area an economic ‘growth pole’ for the northwest geo-political zone.
Using soybeans, manure, organic npk® (compost) and npk fertilizer to enhance soil nutrients, organic matter and grain yield of sorghum in makurdi, nigeria
Authors: S.T Ter
Published: December 2022

A field trial was conducted in 2016 and 2017 at Commercial Crop Farms of the University of Agriculture, Makurdi to evaluate the effect of manure, compost and NPK fertilizer under soybeans-sorghum mixed cropping. The experiment consisted of three (3) levels of poultry manure (0, 2.0 and 3.5 t/ha), three (3) levels of compost manure (0, 0.2 and 0.4 t/ha) and three (3) levels of NPK (0, 30 and 60 KgN/ha). Soybean was intercropped with sorghum as a nitrogen fixer in selected plots. The experiment was laid out in a Randomised Complete Block Design and replicated three (3) times. Soybean as nutrient source marginally enhanced organic matter and nutrients content in the soil. Poultry manure retains the highest concentration of OM and nutrients in the soil compared to compost and NPK fertilizer. Also, grain yield of sorghum was significant at (P<0.05) with manure and fertilizer application; NPK fertilizer at 60 kg N/ha in sorghum-legume mixture gave the highest yield (1035.0 kg/ha and 1138.4 kg/ha in 2016 and 2017 respectively). The lowest yield was obtained from non fertilizer treatments. The concentration of organic matter and plant nutrients elements in the soil and grain yield of sorghum were enhanced by addition of manure and fertilizer. Therefore, sustainable cultivation of sorghum is possible via the use of fertilizer, manure and a nitrogen fixer are used as soil amendments

The study was carried out to investigate the use of New media for communication among extension agents and farmers in Oyo State, Nigeria. Forty Extension agents and eighty farmers were randomly selected. Data collected were subjected to descriptive analysis using frequencies and percentage. Majority of extension agents (90.0%) were aware of Social Media. Farmers (97.5%) were aware of Agricultural websites. Extension agents (85.0%) have access to Agricultural Blogs, farmers (87.5%) have access Agricultural Websites. Extension agents also have high access (75.0%) to New media and farmers have high access (67.5%) to New media. Majority of Extension agents in the study area have a benefit derived from the use of New media as to enhance their job commitments. Farmers have the benefits derived from the use of New media as it saves time and money. Majority of Extension agents in the study area used new media to source for information on farmers’ livelihood and possible ways of improving their living standards. Extension agents (55%) and also farmers (60.0%) have high level of use of new media. It is recommended that Extension agencies should organize in-service training for the staff on skill acquisition and importance of New media use in sourcing and disseminating innovation and also the Nigerian government should address the problem of using the New media in agricultural and rural development via focusing on providing broadband connectivity and a content centric development approach particularly in the rural areas.

Published: December 2022

Climate variability has been a major threat to achieving sustainable food production in many countries, including Ghana. This is attributable to insufficient and erratic rainfall coupled with increasing temperature. This study examined the perceived effects of rainfall and temperature variability on yields of cereal crops in the Mion District of the Northern Region. The study reveals that farmers in the Mion District have experienced changes in climatic conditions evident in high temperatures and low rainfall. The study also reveals that rainfall and temperature variability adversely affect the yields of cereal crops such as rice, maize, and millet. The effect could manifest in either yield reduction or total crop failure of cereals. The study also showed that factors that enable farmers to respond to impacts of rainfall and temperature variability are Agric extension services, application of fertilizer, irrigation farming, use of improved seeds, and favourable government policies such as subsidies and credit facilities.   The study, therefore, concludes that yields of cereal crops are adversely affected by rainfall and temperature variability. However, farmers resort to Agric extension services, application of fertilizer, irrigation farming, use of improved variety of seeds, and favourable government policies in response to the impacts of rainfall and temperature variability. The study recommends that government should employ more extension agents and construct more irrigation facilities in the Mion District to reduce the adverse effects of climate variability on yields of cereal crops.

Authors: KORUN Jale , ULUTAŞ Aycan
Published: December 2022

In the study, in addition to the antibacterial effect of astaxanthin on Aeromonas hydrophila and A. sobria strains, the presence of virulence genes (Aero, act, ast, and hylA) and antibiotic resistance genes (tetC and sulI) in the strains was investigated. Antibiotic profiles of the strains were also investigated as part of the study. Strains were identified by conventional biochemical tests and PCR assay using a 16S rDNA primer pair specific for A. hydrophila. According to the results of bacteriological and molecular studies, two of the six Aeromonas strains were identified as A. hydrophila and four of them as A. sobria. The Aero virulence gene and the act virulence gene were found in all strains, while the ast and hylA virulence genes were detected only in A. hydrophila strains. All strains were resistant to chloramphenicol, tetracycline, nalidixic acid, and ampicillin in the standard disk diffusion test. Although all strains showed resistance to tetracycline and moderate resistance to oxytetracycline in the antibiogram tests, tetC antibiotic resistance gene was not detected in the strains and sulI antibiotic resistance gene was not detected in the strains. In the study, acetone solutions containing 0.1 g and 0.5 g of astaxanthin were found to have an antibacterial effect on A. hydrophila strains. Acetone solutions containing 0.1 g, 0.5 g, and 1.0 g of astaxanthin showed antibacterial effects on A. sobria strains. It was found that 0.1 g, 0.5 g, and 1.0 g astaxanthin solutions prepared with methanol and distilled water had no antibacterial effects on the strains.

Published: December 2022

Emotions form an essential and fundamental aspect of our lives. What we do and say reflects some of our feelings in some way, though not directly. We must examine these feelings using emotional data, also known as affect data, to comprehend a person's basic behavior. Text, voice, facial expressions, and other data types can be included. Since social networking websites have become so popular, many individuals have started reading the material on these numerous sites.Twitter is one of these social networking sites. People's feelings and thoughts about a subject reveal positive, negative, and neutral emotional values. Doing sentiment analysis on Twitter is a very important and challenging task. In this study, we aim to investigate the sentiments of Bitcoin and provide an overview of its effect on the value of Bitcoin by utilizing the power of deep learning architectures and machine learning methods. The study collected tweets in English shared on Twitter between December 12, 2021, and March 13, 2022. First, people's feelings about Bitcoin were assessed using TextBlob, a natural language processing (NLP) tool. Then, it was done using basic machine learning algorithms for sentiment classification and CNN, LSTM, and BiLSTM deep learning architectures that we modeled. However, deep learning models were tested separately with the TF-IDF and Glove word embedding approaches. Experimental results prove the success of deep learning architectures using the Glove word embedding approach.

Sobre las pinturas del colegio de San Teodomiro de la Compañía de Jesús de Carmona
Authors: García Baeza Antonio , Martín Pradas Antonio
Published: December 2022

Dentro del gran patrimonio que poseían los colegios de la Compañía de Jesús en el momento de su expulsión, el más difícil de rastrear es el patrimonio eclesiástico, concretamente los bienes muebles. Este grupo está compuesto por una extensa tipología que varía en función del soporte y del uso. Tras la expulsión de la orden de sus reinos, Carlos III y su consejo planificaron un sistema de inventarios de todo tipo de bienes, pasando las pinturas a ser propiedad de la Corona. En el presente artículo nos vamos a centrar en el ámbito de la pintura, gracias al inventario que se realizó de las dependencias del colegio de San Teodomiro de Carmona en 1767. Algunas de ellas fueron vendidas, otras cedidas a instituciones como la universidad, arzobispado e incluso a parroquias y conventos locales. Por último, las de pintores famosos pasaron a engrosar los fondos de las academias reales.
Sesenta años es un corto periodo de tiempo. Luis Gordillo y el amor al presente
Authors: Torres Jurado Juan Jesús
Published: December 2022

Indispensable en toda retrospectiva del arte español de los últimos sesenta años, Luis Gordillo, a salvo de modas o poderosas tendencias destinadas a ser superadas, ha naturalizado una suerte de huida hacia delante, con cierta causticidad e irreverencia, para atreverse con caminos antes inexplorados en nuestro contexto. En muchos sentidos, su construcción de imágenes es pionera y fundacional hasta convertirse en referente en las nuevas perspectivas de la imagen pictórica y de naturaleza fotográfica. No obstante, en consonancia con los logros creativos del artista en los últimos años, resulta pertinente una ampliación de aquellos estudios para comprender la obra de Gordillo desde un plano filosófico menor, acaso psíquico; desde la inmanencia de una obra cargada de análisis, conquista y rebelión temporal.

Nuevos datos del arquitecto y escultor Luis Ortiz de Vargas y sus obras realizadas en Écija y Córdoba
Authors: Gallardo Montesinos Rafael
Published: December 2022

En este artículo se proporcionan datos inéditos de Luis Ortiz de Vargas sacados de los archivos astigitanos, los cuales nos acercan a la fecha de su nacimiento y a sus inicios en el antiguo reino de Sevilla. En la ciudad de Écija trabaja bajo el mecenazgo del jurado Cristóbal Gómez, quien actúa como su principal pagador y fiador de su morada, y le encarga las primeras obras de renovación de su capilla. También realizó trabajos para conventos e iglesias, de los cuales algunos se conservan, aunque se creían perdidos. Del retablo mayor de Santa Cruz de Écija creemos que pertenece el san Crispín; y del retablo mayor de los carmelitas descalzos de la misma localidad, pervive la estructura de los cuatro fustes clásicos con guirnaldas. En su primera etapa sevillana también trabajó para las localidades de Carmona y Córdoba. De esta última se ha podido identificar el retablo que hizo para la catedral, y que se mencionaba en un contrato de obligación de una mesa de caoba para Francisco de Herrera el Viejo.

Published: December 2022

Es a partir de mediados del siglo XX cuando se comienza a redescubrir el legado artístico del periodo virreinal en Panamá y, por ende, toman auge disciplinas que emprenden investigaciones desde lo arqueológico, lo socio-religioso y lo etnográfico. La historiografía del arte panameño, a lo largo del periodo virreinal y, en especial, del arte realizado por los indígenas, presenta grandes vacíos. Este es el principal motivo del presente estudio, que dará pie a nuevas propuestas interpretativas en las simbologías e iconografías de las piezas de estilo barroco ubicadas en el Museo de Arte Religioso Colonial en el casco antiguo, y sus conexiones con las escuelas talleres de la península de Azuero y las provincias de Chiriquí y Veraguas, como sitios de producción artística virreinal e instruidos primeramente por las órdenes mendicantes.

Published: December 2022

Introduction: Dense breasts are common in Asian women and they limit the sensitivity of mammography. This study evaluates the performance of supplementary breast ultrasound screening in Asian women with dense mammograms. Materials and Methods: The study was approved by the hospital’s Institutional Review Board. A prospective clinical trial was performed between September 2002 and November 2004. Asymptomatic Asian women with negative and dense mammograms were offered supplementary ultrasound screening for breast cancer. Ultrasound assessment was categorised as U1 to U4. U1 and U2 cases were recommended routine interval screening mammography. U3 cases were recommended follow-up ultrasound in 6 months and routine interval screening mammography and U4 cases were recommended biopsy. Results: One hundred and forty-one women with mean age of 45.1 years were enrolled into the study. Mean scan time was 13.0 minutes (± 5.6 minutes) for bilateral vs 11.0 minutes (± 1.4 minutes) for unilateral scans. There were 10 patients and 14 patients in the in the U3 and U4 categories, respectively. Two U4 category patients were diagnosed with malignancy—a-6 mm ductal carcinoma-in-situ and a 13-mm invasive ductal carcinoma. The breast cancer detection rate was 1.4%. Sensitivity and specificity were 100% (2/2) and 88.5% (92/104) respectively. The positive predictive value was 14.3% (2/14) and the negative predictive value was 100% (92/92). Conclusion: This pilot study reveals the usefulness of supplementary ultrasound screening in detecting early stage mammographically and clinically occult breast cancers in Asian women with dense breasts. A larger long-term study is, however, needed to assess its feasibility and impact on breast cancer prognosis. Key words: Asian, Breast, Dense, Screening, Ultrasound

Introduction: This study aims to compare the long-term efficacy of 25-gauge vitrectomy to that of intravitreal bevacizumab (IVB) for the treatment of macular edema (ME) secondary to branch retinal vein occlusion (BRVO). Materials and Methods: The medical records of 46 eyes of 46 consecutive patients were reviewed. Twenty-seven eyes underwent 25-gauge vitrectomy (VIT Group) and 19 eyes received 1.25 mg of IVB (IVB Group). The best-corrected visual acuities (BCVAs) in logarithm of minimum angle resolution units and central macular thicknesses (CMTs) were evaluated before and 3, 6, and 12 months after the initial treatment. Results: There was no significant difference in the pre-treatment BCVA and CMT between the 2 groups. In the VIT Group, the preoperative BCVA was 0.59 and the CMT was 587.3 μm and the BCVA was 0.35 and the CMT was 286.6 μm, 12 months after the vitrectomy. Both values were significantly (P <0.05) better at 12 months than the preoperative values. In the IVB Group, the average number of IVB was 2.4 during the 1-year period. The BCVA was 0.69 and the CMT was 590.9 μm before the IVB, and the BCVA was 0.36 and the CMT was 360.1 μm, 12 months after the initial IVB. The improvements of these 2 parameters were significant (P <0.05) at 12 months after the initial IVB. The differences in the BCVA and CMT at 12 months between the 2 groups were not significant. Conclusion: These results suggest that the 25-gauge vitrectomy and IVB have similar effects in improving the BCVA and CMT in eyes with ME secondary to BRVO. However, IVB often required several injections to preserve the improvement. Key words: Eye, Vascular endothelial growth factor
Prospective Evaluation of Argon Gas Probe Delivery for Cryotherapy of Bone Tumours

Published: December 2022

Introduction: Cryosurgery for tumoural ablation traditionally involves instilling liquid nitrogen into a tumoural bed. The inability to control precise delivery can result in potentially disastrous consequences of skin necrosis and nitrogen gas embolism. In this study, we evaluated a probe-based closed cryosurgical system, which eliminates these risks. Materials and Methods: We performed a prospective evaluation of 36 cases of bone tumours treated with a probe-based cryosurgical system at the National University Hospital, Singapore. Cases consisted of patients with benign aggressive tumours (42%), primary malignant bone tumours (25%) and bone metastases (33%). In primary bone tumours, the aim of therapy was cure. In bone metastasis, the aim of therapy was palliation defi ned as the relief of symptoms for the patients’ remaining lifetime. Results: In the primary bone tumour group, no recurrences were reported. In the metastases group, where the intention was palliation, there were 3 cases of radiological relapses (P = 0.02) and 2 clinical relapses. Kaplan-Meier evaluation showed a statistically significant tendency for radiological relapse in metastatic disease versus primary disease (P = 0.02). Median time for relapse free survival in the metastatic group was 17 months (P = 0.01). There were 4 deaths in the metastatic group due to progression of disease unrelated to the index region of cryosurgical treatment. There were no deaths in the primary bone tumor group. We had 2 complications from this therapy involving fractures through the cryoablated segments. One case healed spontaneously and the other was most expediently managed with a shoulder hemiarthoplasty. There were no skin burns or embolic complications. Conclusion: Good clinical efficacy with probe delivered cryotherapy has been shown in this group of 32 patients with cure in all primary disease. Relapse occurred in only a small proportion of patients with bone metastasis.

Published: December 2022

Introduction: Suicide is one of the most tragic problems medical schools are facing today. It is an issue that has not escaped medical schools in either developing or developed nations. To combat this trend, medical educators require efficient and effective strategies for the immediate identification of students who are at an elevated risk of harming themselves. Materials and Methods: National Yang Ming University medical students were surveyed on various demographic, academic, personal, and extracurricular subjects as well as assessed for suicidal ideation. In addition, students completed the Chinese Health Questionnaire (CHQ, a translated and modified version of the General Health Questionnaire, GHQ), and the Taiwanese Depression Questionnaire (TDQ, a translated and modified version of the Center for Epidemiologic Studies’ Depression Scale, CES-D). Results: The rate of suicidal ideation was significantly higher in second year students as opposed to first year students (P <0.01). Students of lower socioeconomic status (P = 0.04), with non-inflammatory joint pain (P = 0.02), with headache (P = 0.047), with sleep disorders (P = 0.04), who scored as depressed on the TDQ (P <0.01), and/or who scored abnormally on the CHQ (P <0.01) were all significantly more likely to have experienced suicidal ideation. Conclusion: A number of groups at high risk for suicidal ideation, and thus in greater need of support, were identified. Suicide intervention programmes and depression counselling should target older students and students of lower socioeconomic status. Students presenting to university clinics with non-inflammatory joint pain, headache, and/or sleep disorders should be evaluated for suicidal tendencies. The TDQ and CHQ are potentially valuable screening tests for early detection of potential suicidal students.

Education Production Function In Senegal At The Primary Level: Box-Cox Transformation (1964)
Authors:   LARES (Economics Research Laboratory) Gaston Berger University of Saint-Louis
Published: December 2022

This paper proposes to estimate the educational production functions of Senegal from the PASEC 2014 data at the primary level at the beginning and end of schooling by the BOX-COX (1964) transformation. We do not impose a linear functional form a priori but propose to determine it using the BOX-COX model. The results obtained indicate that the widespread use of the linear form is not appropriate, at least with respect to the Senegalese data. On the other hand, the use of this transformation at the beginning and at the end of the schooling period yielded interesting results.

What does Social Justice Mean for Education in Rural Australia
Authors: Morrow Ann
Published: December 2022

I would like to review some of the major initiatives currently being undertaken across education, i.e. from primary schools to higher education, and including lifelong education and training. I will attempt to show how the needs of rural Australia are being considered in these developments. Also, I will touch on what I believe is still problematic in our approaches. Underpinning this is my own personal belief that social justice issues need to be foremost in our minds whenever we are making changes within education. Each new development carries with it the potential to reduce or exacerbate inequity or problems of access. I think we are getting better at identifying the likely impact of changes but that doesn't mean to say that we yet have it right.
Catering for the needs of pre-school age children in rural areas: A case study
Authors: Clyde Margaret
Published: December 2022

In 1985 the then Minister for Community Services (Victoria), the Hon. Caroline Hogg, announced a change of policy in relation to preschool services in Victoria; all children were to have a year of "kindergarten type experiences" in the year before school, and existing playgroups for two year olds were to be phased out, while two years of kindergarten for some children was to become the exception. This policy came about for two reasons; firstly, as a way of implementing the Cain Labor Government's policy of social justice and equity, and secondly as an attempt to be more financially accountable. While both these objectives, in hindsight, may have a somewhat hollow ring today, they brought great changes to the preschool programs of Victoria which had been established nearly a century before by voluntary organisations in response to inner city poverty and need. It meant that an effort would be made to ensure that children in isolated and/or rural pockets of Victoria were to be included in the sessional kindergarten program and that the traditional "four sessions of two and a half hours per week at a place called a kindergarten" might not be seen to be appropriate in terms of travelling distance involved for parents or children, or affordable in terms of the best use of a rapidly declining budget.
Preparing pre-service teachers for rural appointments
Authors: Jenkins Kathy , Cornish Linley
Published: December 2022

Pre-service teachers need to be prepared to teach in both rural and urban contexts. Preparation to teach multi-grade classes in rural schools is excellent preparation for teaching any class, including urban single-grade classes. Based on our previous research and experience, we designed a unit to prepare our pre-service teachers for the issues they may face in their employment and especially in rural schools, including multi-grade teaching, coping with isolation, working as a casual teacher, and communicating with parents and caregivers. There are significant issues that are distinct in rural and urban contexts, including how metrocentric departmental policies can emphasise the rural/urban divide.
