Authors: Agasi Satri Yusasra , Ulupi Niken , Afnan Rudi , Arifiantini R. Iis
Published: March 2024

Quails are classified according to their immunity to different IgY concentrations. Quail IgY concentrations range from 0 to 1200 Âµg ml-1, and these IgY concentrations may affect production and reproductive performance. This study aimed to analyze IgY concentrations in male quail and to compare production and reproductive performance at different IgY concentrations. Forty-two male quail at five weeks of age participated in the study, including 29 quail with low IgY concentration (210-393 Âµg ml-1)Â Â  and, 13 with intermediate IgY concentration (403-564 Âµg ml-1). The observed productive performances were feed intake, initial body weight, final body weight, weight gain, feed conversion, morbidity, and mortality. In addition, this study observed testicular weight and macroscopic and microscopic semen quality for reproductive traits. Differences in production and reproductive performance of each group were analyzed using an independent-sample t-test. The result showed that male quail with different IgY concentrations were equal in all productive traits (P0.05). This means that male quail with low IgY and medium IgY concentrations are equally good. Testicular weight, semen color and pH were identical at different IgY concentrations. Quails with low IgY concentrations have better sperm consistency, which is related to the weight of the testes, which are heavier in quails with low IgY concentrations than in those with moderate IgY concentrations. This consistency is related to the concentration of sperm in the semen. The result concludes IgY concentrations in male quail did not affect production performance. Quails with low IgY concentration had thicker sperm consistency and higher sperm concentration.

The research aimed to evaluate the effect of Zn supplementation in diet of Sikumbang Janti female duck on its performance, carcass, digestive organs, and intestinal morphology. The study used 96 female ducks aged 8 weeks. This research used a completely randomized design with four treatments (0, 30, 60, and 90 mg Zn/kg), each treatment was repeated four times. Performance, carcass, digestive organs, and intestinal morphology were observed. The results showed that Zn supplementation significantly (P0.05) affected body weight, body weight gain, feed conversion ratio, carcass weight, abdominal fat, and intestinal morphology, but it did not affect (P0.05) feed consumption, carcass percentage, and digestive organs. In conclusion, supplementation of 60 mg Zn/kg in the diet improved performance, intestinal morphology, and the health of visceral of Sikumbang Janti female ducks aged 8 to 16 weeks.

Authors: Merzah Layth H , Mohammed Rihab G , Rhadi Fadhil A , Al-Thuwaini Tahreer M
Published: March 2024

Livestock intramuscular fat content is determined by fatty acid synthase (FASN).Â  The fatty acid profile of the fat is of relevance to human health. Â Thus, this study explores the relationship between the polymorphism of the FASN gene in Awassi sheep and its impact on fatty acid composition.Â  The study used 100 Awassi rams, ranging in age from 1 to 2.5 years.Â  Molecular DNA was isolated from each blood sample; genotyping, sequencing reactions, and in silico tools were subsequently used to confirm the variants in amplified fragments. Â The results revealed two genotypes (GG and GA) of the ovine FASN gene (exon 2).Â  The novel missense c.186 GA was identified in the genotype GA. Â The GA genotype had significantly (P0.05) increased intramuscular fat, higher unsaturated fatty acid content, and lower saturated fatty acid content than the GG genotype.Â  Cumulative in silico analysis indicated a detrimental effect of the SNP c.186 GA on FASN activity.Â  The intramuscular GA genotype of Awassi sheep had a low saturated content relative to unsaturated fats.Â  The result confirmed that the c.186 GA SNP in ovine FASN gene variation is potentially helpful in assessing carcass traits, and this might lead to a more efficient selection of animals with healthier fatty acid profiles, resulting in higher-quality meat.

The Role of The State in Diversifying and Expanding the Brazilian Energy Matrix: an Analysis of Legislation
Authors: Morais Paulo Roberto Ribeiro , Souza Júnior Carlos Moreira de , Lobão Jocimara Britto Souza , Lentini Carlos Alessandre Domingos
Published: March 2024

Despite having an essentially renewable electricity matrix, the dependence on hydropower, in the current climate risk scenario and the associated environmental and social impacts, point to the need to diversify energy generation in Brazil. To this end, state action is fundamental for designing and implementing public policies for the country's energy matrix. However, this diversification does not occur at the desired speed and scale. Thus, this article analyses the Brazilian regulatory environmental policies to assess the participation of the Federal constituencies, States, and municipalities in scaling renewable sources in the national electricity matrix. The research revealed that specific legislation on energy is scarce, and much of what is applied is taken from the general environmental legislation. We noticed that, by constitutional imposition, the Federal constituencies have the legislative competence on the theme and, therefore, establish norms and general rules, while States and municipalities act marginally, especially in fiscal matters and environmental licensing. The need for more objectivity, standardization, and the non-existence of specific technical criteria in the norms about energy use. We also verified that most of what was legally established constitutes government programs, not state policies. It is necessary to extend the participation of states and Municipalities in elaborating national energy use plans and in the revision and technical standardization of the licensing norms. These gaps must be filled so sustainable development, a principle established in the Constitution, is strengthened and made possible, with the participation of States and Municipalities.
An investigation of self-sensing and mechanical properties of smart engineered cementitious composites reinforced with functional materials
Authors: Al-Dahawi Ali Majeed , Abdullah Raid D. , Joni Hasan Hamodi
Published: March 2024

In this study, hybrid functional fillers were used to create an electrical network that is used to develop self-damage sensing ability within conventional cementitious mixtures. This electrical network was used to examine the self-sensing properties of cementitious composites under different loading scenarios such as compression, splitting tensile, and cyclic loading for three ages, those are 7, 14, and 28. With the help of a single type of functional filler or fiber, the self-sensing capabilities of the majority of previous works are demonstrated. This study incorporates two types of functional fillers for sustainability and low cost: micro-scale carbon fibers (CF) and waste iron (Ir) powder in the form of microparticles. The purpose of the current work is to fill up the subject’s gap using two different types of functional fillers as a hybrid form. Three hybrid proportions of a micro-scale CF (vol% of mixture) and waste iron powder (Ir) (wt% of cementitious materials) are utilized. These are (0.33, 15), (0.67, 10), and (1.00, 5), respectively. Unlike carbon-based materials, polyvinyl alcohol is used as a mechanical reinforcing fiber 2% by volume of the cementitious mixture. Additionally, a control combination without any fillers has been created. The electrical resistivity of the fabricated samples was monitored during various loading applications for every second to confirm their self-sensing capabilities. Regarding the fractional change in electrical resistivity, the self-sensing behavior was superior for mixes containing high dosages either of waste iron powder or CF in the same hybrid matrix. Quite the contrary to that, the piezoresistivity was modest in the middle hybrid ratio.
Stability analysis and numerical results for some schemes discretising 2D nonconstant coefficient advection–diffusion equations
Authors: Appadu Appanah Rao , Gidey Hagos Hailu
Published: March 2024

We solve two numerical experiments described by 2D nonconstant coefficient advection–diffusion equations with specified initial and boundary conditions. Three finite difference methods, namely Lax–Wendroff, Du-Fort–Frankel and a nonstandard finite difference scheme, are derived and used to solve the two problems, whereby only the first problem has an exact solution. Stability analysis is performed to obtain a range of values of the time step size at a fixed spatial step size. We obtain the rate of convergence in space when the three methods are used to solve Problem 1. Computational times of the three algorithms are computed for Problem 1. Results are displayed for the two problems using the three methods at times

T
=
1.0

T=1.0

and

T
=
5.0

T=5.0

. The main novelty is the stability analysis, which is not straightforward as we are working with numerical methods discretising 2D nonconstant coefficient advection–diffusion equation where many parameters are involved. The second highlight is to determine the most efficient scheme from the three methods. Third, there are very few published studies on analysis and use of numerical methods to solve nonconstant coefficient advection–diffusion equations, and this is one of the very few rare articles treating such topics.
Does Building Identity Still Exist? Does The Building Identity Needs to be Redefined?
Authors: Švigelj Aleš , Lazić Marko , Fikfak Alenka , Novljan Tomaž
Published: March 2024

The article presents the redefinition of the continuity and visibility of the elements of building identity in recent buildings, in the context of the architectural regions and landscapes defined by Prof. Peter Fister in the 1990s. The mass of »self-build« interventions in the 1980s led to a break in the continuity of the transfer of traditional elements of the built heritage to new buildings - both at the level of the individual building and at the level of the settlement. The article describes the process of discovering and, with the help of modern software tools, evaluating those examples of recent construction where, despite the influence of various trends, it was possible to identify the preservation of traditional building identity elements. The research at the settlement and single building level was carried out in the area of Prebold in the Savinjsko-kozjanska architectural region, while the study of individual buildings included examples of good practice from the whole territory of Slovenia. At the same time, Fister’s »inventory cards« were upgraded in terms of content, which now more systematically define the position of the building within the settlement and its volumetric and planar visual elements, which are the carriers of identity.
La Fenomenología del Espíritu como modelo de interpretación de la subjetivación social
Authors: Bueno Kurle Adriano
Published: March 2024

En este artículo defiendo la consideración de la Fenomenología del Espíritu como modelo para pensar los procesos de subjetivación en la sociedad contemporánea, especialmente considerando la noción de fracaso de la experiencia y las figuras de la autoconciencia. Para ello, divido la presentación en tres etapas: En primer lugar, a partir de la propuesta del filósofo brasileño Marcos Nobre, en su libro Como Nasce o Novo [Cómo Nace lo Nuevo], de tomar la Fenomenologíacomo modelo filosófico para la Teoría Crítica contemporánea (a partir de su consideración, en la tradición dialéctico-crítica, como obra fenomenológica que describe procesos de subjetivación, en contraste con las obras enciclopédicas), evalúo críticamente su libro y argumento que no presenta la relación entre su propuesta para la Teoría Crítica y su análisis de la Introducción de la Fenomenología. En segundo lugar, considero útil su hipótesis, por lo que me aproximo a la Lucha por el Reconocimiento de Honneth (tomada por Nobre como uno de los modelos de obra fenomenológica), y critico su posición en relación con la Fenomenología del Espíritu, en particular por no reconocer que esta obra implica una radicalización, y no un debilitamiento, de la noción de intersubjetividad, en relación con los escritos anteriores de Hegel. Propongo la noción de fracaso de la experiencia como guía para comprender los conflictos sociales, en lugar de la lucha por el reconocimiento, considerándola un concepto más amplio, que abarca el reconocimiento. Por último, considero la autoconciencia en la Fenomenología como un modelo para comprender las figuras sociales y sus problemas, concluyendo que esta idea puede ser útil como herramienta para interpretar la sociedad contemporánea, especialmente la brasileña ante el crecimiento de la nueva extrema derecha.
El joven Hegel y las sociedades premodernas: barbarie y eticidad.
Authors: Huesca Ramón Fernando
Published: March 2024

El joven Hegel influenciado por Rousseau y Herder, llegó a un entendido crítico de la Modernidad capitalista que no colocaba al mundo civilizado por encima de modos premodernos de cultura, sino que admiraba su cohesión política y diversidad cultural y erótica. De este horizonte intelectual hegeliano se obtiene una crítica radical al cristianismo y a las pretensiones de superioridad de la civilización moderna frente a otros mundos de vida. En la evolución intelectual de Hegel la inserción de la economía política clásica marca un giro teórico que acaba en la concepción de madurez de la eticidad y del desarrollo civilizatorio. Hegel no dejará de ser un crítico tenaz de la sociedad capitalista y sus efectos coloniales y eróticos, pero abandonará su republicanismo de juventud, su posición herderiana frente a los mundos salvajes y bárbaros, y sus posiciones teológicas grecófilas.
El tema del multiverso en el filme Everything Everywhere All at Once (2022) y en «El Aleph» de Borges: un estudio comparativo
Authors: Xi Yue
Published: March 2024

El filme Everything Everywhere All at Once (Todo a la vez en todas partes, 2022) ha acaparado la atención del público y de la crítica gracias a su deslumbrante complejidad estilística. Su tema central, el multiverso, así como su estilo narrativo recuerdan a un célebre cuento de Jorge Luis Borges, «El Aleph», publicado en el volumen del mismo título en 1949. En este trabajo se compararán estas dos obras en lo que respecta a sus aspectos temáticos, estructurales y narratológicos, intentando establecer una relación entre estos planos y explorar cómo se reproduce lo infinito del multiverso. El estudio concluye que la película y el cuento son muy similares en la estructura y temática, pero ambos utilizan diferentes técnicas de expresión para lograr el efecto de enumeración caótica.

Published: March 2024

This paper presents the first experiences of the use of an online open-source repository with programming exercises. The repository is independent of any specific teaching approach. Students can search for and select an exercise that trains the programming concepts that they want to train and that only uses the programming concepts they already know. Then, they can submit their solutions and get automatic feedback from the system. We analyzed quantitatively how students used the system by inspecting the logged actions of the students using the system. We also did a qualitative analysis by interviews, to find out how the students appreciated the use of the repository and to get feedback for improvements. We focused on how students select exercises as finding the exercise that fulfills the training needs of a student is the innovative part of our repository.
Effect of dietary carbohydrate type, biological sex and phenotype on glycemic responses in wistar fatty rats
Authors: Tulp Orien L
Published: March 2024

To determine the effects of dietary carbohydrate type, biological sex, and phenotype on systemic glycemic responses in a rat strain that Is highly predisposed to development of obesity+NIDDM, groups of adult male and female lean and obese Wistar Fatty Rats were fed nutritionally complete isoenergetic diets containing 54% carbohydrate as cornstarch (ST) or sucrose (SUC) plus other essential nutrients, vitamins, and minerals from 22 until 30 weeks of age. Measures of body weight gain (BWG), Food efficiency ratio (FER), intraperitoneal Glucose Tolerance (ipGTT), fasting insulin to glucose ratios (I: G), and area under the glucose curve (AUC) determined. Results demonstrated that BWG and FER of obese >> lean and was further increased in both phenotypes when fed the SUC diet. The ipGTT responses of obese > lean in both sexes, and that substitution of SUC for ST markedly exaggerated the glycemic responses and glycosuria in both sexes. Fasting of insulin concentrations were greater in obese male than obese female, were further increased when fed the SUC diet and were significantly greater in the obese than occurred in the lean phenotype of either sex. Fasting glucose concentrations of male obese+NIDDM were elevated but remained within normal limits in the remaining groups. The I:G ratios were greatest in Obese+NIDDM male rats, intermediate in the obese+NIDDM female rats, and were within normal range in both lean groups on ST and SUC diets and the AUC of obese > lean of obese sexes and was further increased when fed the SUC diet in both sexes. These results confirm that feeding a high glycemic index sucrose rich diet enhances the efficiency and amount of weight gain and exacerbates the aberrant glycemic responses during ipGTT in the obese+NIDDM phenotype.
Indigenous knowledge in agroforestry promotion: a case from Bandegaun, Indrawati Rural Municipality, Sindhupalchok District, Nepal
Authors: Sharma Suraj , Acharya Parashar , Joshi Murari Raj
Published: March 2024

This research presents the role of indigenous traditional knowledge on agroforestry promotion in Bandegaun of Sindhupalchok district. Both primary and secondary information was collected through a household survey, key informant discussion, focus group discussion, direct observation, and review of agroforestry-related literature, papers, and reports. Agriculture was the main occupation of the respondents with the majority (62%) of the total respondents having a small landholding of less than 0.75 ha. However, about 91% of the total had practiced both agri-silviculture and home gardening, 55% of the total respondents had a Silvi-pastoral system and 27% of the total respondents had a small wood lot of trees. The main indigenous traditional knowledge used by the respondents for the promotion of these agroforestry practices in their farms were knowledge on the palatability of fodder species, knowledge on timber quality, knowledge on propagation by cutting, knowledge on NTFP value, knowledge on cash earning, and knowledge on religious value of tree species. A total of 39 tree species were included in the agroforestry practices of the study areas. Among them were 10 fodder species, 12 timber and fuelwood species, 6 NTFPs, and 11 fruit trees. Each study household on average have grown 4 fruit trees, 47 fodder tree, 19 fuelwood, and timber trees, and an NTFP in their farmlands, which have provided a great contribution to fodder, fuelwood, and timber supply for household use reported by 91% of the total respondents and some respondents (76%) had also generated income from the sale of timber, fuelwood, and NTFPs. Finally, it is recommended that indigenous knowledge-based agroforestry awareness and training programs along with preferred seedlings of good quality should be provided to promote agroforestry in study areas.
Use of composting to produce organic fertilizer from horse stall residues
Authors: Costa Gabriel Dias , de Souza Breno Mourão
Published: March 2024

The development of agriculture in Brazil has changed the role of horses from working animals to animals for sport competition and recreation. Horse breeding is a relevant activity in Brazilian agribusiness and approximately 6 million animals are currently involved in such activity. Recreation and sport horses are usually confined in stalls, where the animals spend the days. A variety of materials are used for bedding horse stalls, such as wood shavings, rice husks and dry grasses. These materials are removed daily or weekly. Horse manure is not well regarded as good plant fertilizer. The present work aims to develop a methodology for the reuse of waste from equine stalls (wood shavings, feces, urine, and animal food remains) through composting, characterizing, and evaluating the potential of the final product as a biofertilizer. For this, beds of 2 horses were used, composed of wood shavings, feces, urine, and food leftovers dropped by the animals on the bedding. Two types of wood shavings were tested – sawdust and chips. After 15 days of confinement, the litter was removed and went through a composting process with daily control of temperature, humidity, aeration, and smell until stabilization of the compost, which occurred after approximately 60 days. After this period, part of the material was collected for analysis of carbon (C) and nitrogen (N) concentration, and C/N ratio. The results obtained indicate that the final compost is suitable for use as organic fertilizer.
Study of the state of the art of the circular economy in Europe
Authors: Gama Ana , Russo M
Published: March 2024

The Circular Economy, an approach to combating environmental challenges and promoting sustainable development, is currently a popular notion within policy and business advocacy groups. The EC notion and definitions are based on a fragmented collection of ideas which are derived from a variety of scientific disciplines and semi-scientific concepts. For this reason, it is the target of much criticism in academic and professional circles. The global economy is getting worse year by year, in 2018, the global circularity was 9.1%, in 2020 8.6% and in 2023, it dropped to 7.2. This means that more than 90% of materials are wasted, lost or remain unavailable for reuse for years, leaving a huge circularity gap: the globe depends almost exclusively on new natural resources. The objective of this article is to identify the state of the art of the circular economy, in addition to discussing the various definitions provided by the literature review.

Published: March 2024

High usage of synthetic plastic will harm the environment due to its difficulties in degrading and harming the environment. Environmentally friendly plastic packaging that can be used is active and intelligent packaging made from starch as one of the innovations in food packaging. The starch extracted from the sago (Metroxylon sagu) fruit can form a thin layer for biodegradable plastic packaging. Addition material such as natural pigment will enhance the biodegradable packaging ability to be active and intelligent. As a natural pigment, betacyanin can be collected from beetroot peel waste, which is rarely utilized. This review aimed to explore the potency of sago starch with betacyanin pigment addition from beetroot peel waste as an active and intelligent packaging plastic material. Sago starch mixed with a plasticizer can form a flexible thin layer (film) and be used as a packaging material. The addition of betacyanin to beetroot peel on sago starch biofilm plays an important role as a sensor through colour change due to its sensitivity to pH changes in spoiled chicken meat products. Sago starch and beetroot peel have excellent potential to be applied as smart packaging innovations.

Published: March 2024

The crystal morphology, chemical composition and mineral inclusions of large Nb-rutile polyhedra from chamber pegmatites of Volyn region were studied. X-ray data for one niobium rutile crystal were also obtained. The sizes of twinned black crystals of the mineral are from 10 to 35 mm. They are interbedded with clevelandite and rare relict microcline. Simple forms of crystals: tetragonal prisms {110} and {100}, dipyramid {111} and sometimes pinacoid {001}. The habit of the crystals is dipyramidal and dipyramidal-prismatic, the shape of the crystals is isometric and short-prismatic. The faces of the prisms are covered with parallel hatching in the vertical belt [001], the faces of the dipyramids are covered with trigon overgrowths. Crystals are twins according to (101), some of them are irregular growths of twins. The unit cell parameters for the studied niobium rutile crystal are a = 4.6159 Å, c = 2.9715 Å. The chemical composition of the mineral, the content of the main components, in mass. %: TiO2 — average 76.16, Nb2O5 — up to 20.45 (average 12.77), Ta2O5 — up to 4.92 (average 3.49) and FeO — up to 6.61 (average 4.56). Mineral inclusions in Nb-rutile crystals are columbite, ilmenite, cassiterite, Fe-phase, W-phase, and quartz. A comparison of the morphology of Nb-rutile from crystalline rocks of Ukraine was made and the dependence of their shape on their chemical composition was analyzed. The probable temperature of the mineral formation lies within the crystallization parameters of clevelandite — approximately 300-400°С.
Amphiboles of Alkaline-Ultrabasic Rocks from North-Western Part of the Ukrainian Shield
Authors: Tsymbal O.Yu. , Kryvdik S.G.
Published: March 2024

Different magnesian amphiboles — pargasites, Ca-Na- and alkaline ones (richterites, Mg-kathophorites, Mg-taramites, Mg-riebeckites, Mg-arfvedsonites and intermediate varieties) of alkaline-ultrabasic rocks (hypabyssal intrusions and dikes) from North-Western part of the Ukrainian Shield are studied and analyzed (mainly microbe method). Some pargasites and richterites are characterized by increased or high TiO2 contents (2.9-3.2%). In studied region more enriched in iron and titanium amphiboles (ferri-kaersutites) rarely occur too in veins rocks of essexite composition. Chemistry of amphiboles depends on types of rocks and erosion of their intrusions. Low aluminian and alkaline amphiboles are characteristic for at least eroded intrusions (dikes) whereas in more eroded and more crystallized hypabysal intrusions amphiboles with higher aluminium of pargasite composition form. Such diversity of studied amphiboles is caused by composition of alkaline-ultrabasic melts and some different depth of their crystallization.

The aim of the present study was to analyze the effects of 4 different surface treatments, on the crystallographic characteristics of Ultra-Translucent Zirconia. Fully sintered zirconia specimens of highly translucent yttria partially stabilized zirconia (Y-PSZ) (KATANA UTML) were divided into four experimental groups and a control group (n=10). Each group received one of the following surface treatments: sandblasting with 50µm alumina particles (Al₂O₃), sandblasting with 110µm alumina particles, and grinding with a rotary high-speed turbine with and without water irrigation. For each sample, x-ray diffraction was carried out to analyze peak intensity, calculate the crystallite size, and detect the presence of compressive and tensile stress. Surface roughness was measured on all specimens using a standard scanning profilometer. Additionally, scanning electron microscopy (SEM) was performed to qualitatively analyze the surfaces of the specimens. Statistical analysis included repeated measures analysis of variance and post hoc Tukey test (p≤0.05).  The control group exhibited the highest crystallite size (323nm). All surface treatments led to a reduction in the crystallite size, with the most significant reduction observed in the groups subjected to sandblasting with 110µm alumina particles and high-speed grinding with irrigation. Sandblasting with 50µm alumina particles resulted in less transformation of the crystallite size. A general tendency of the diffraction peaks to shift to a lower angle can be observed in the experimental groups, indicating the presence of compressive stress on the samples. Profilometry revealed higher roughness in the ground samples (6,14µm and 6,57µm) compared to the sandblasted groups (2,93µm and 2,02µm). The crystal domain size showed a tendency to decrease after the surface treatments. Sandblasted samples, as well as ground samples without irrigation, exhibited compressive stress. Sandblasted samples had lower surface roughness compared to the ground samples. Sandblasting with 50µm alumina particles caused the least decrease in crystallite size.

Az 1-es típusú diabetes mellitus krónikus lefolyású, progrediáló természetű
autoimmun betegség. A genetikai, immunológiai és a kezdeti anyagcsere-eltérések
jóval megelőzik a klinikai tünetek jelentkezését, ami már régóta felvetette
annak lehetőségét, hogy a betegség kialakulását késleltessük, megakadályozzuk,
esetleg visszafordítsuk. Sajnos a prevenciót célzó klinikai vizsgálatok sokáig
nem hoztak átütő sikert. A közelmúltban azonban az immunológiai kezelés elérte
azt a stádiumot, amelyben az intervenció előnyei meghaladják a kezeléssel járó
kockázatot. E lehetőségek napi gyakorlatba ültetése, az inzulinkezelés
késleltetésének lehetősége át fogja formálni a betegség kezelésének, illetve az
1-es típusú cukorbetegség tekintetében a nagy kockázatú betegek felkutatásának
eddigi stratégiáját. A szerzők összefoglalják az e kórforma immunterápiájával
kapcsolatos legfontosabb ismereteket. Orv Hetil. 2024; 165(10): 363–369.

Published: March 2024

This paper presents the findings on the respondents’ perceptions of trainees’ competency after completing training. A survey was conducted among 329 respondents from 13 police stations in the Johannesburg policing area using a questionnaire. The findings revealed that contextual factors, namely effectiveness, training environment and trainer’s skills as well as adequate resources towards development have a positive impact on the programme conducted at the training centres. Furthermore, the findings highlighted that the respondents were of the view that, since the inception of new methods of training after the 1994 democratic elections, the South African Police Service (SAPS) had demonstrated a progressive development towards responding to community matters. However, there were gaps in the training and development programmes such as lack of resources, the blanket approach to training and the training models focusing on current challenges rather than future trends. To address these challenges within the SAPS and ensure that there is effective training and development for organisational performance, there is a need to ensure that there are adequate resources for training and development. The training and development procedures within the SAPS also need to adopt international standards. The management at the Johannesburg Training Centre also needs to come up with an effective strategy to identify the needs and skills gaps of employees and ensure that these are addressed in an ever-changing and improving training and development strategy. This study provides critical input and makes a contribution to the literature related to training in the SAPS in South Africa.

Tarkovsky's Napes
Authors: Tavares Pavel
Published: March 2024

Tarkovsky’s Napes begins with a study of Tarkovsky’s signature "nape" shot before moving into a more personal examination of crisis. Like many video essays, this film shifts modes of address as it transitions from subject to subject. Several questions came up, personal and general, while making this video. Is it an anti-fan video from a very devoted fan? Is it really a video essay? How far can a video-essay reveal something about the one being analysed but above all about the analyser?
Why VR Does Not Promote Empathy
Authors: Eitzen Dirk
Published: March 2024

In a famous a 2015 TED Talk, filmmaker Chris Milk called VR an “empathy machine,” a term that quickly caught on with VR producers and audiences, eager to tout the emotional impact of the new medium. In fact, even though VR documentaries can create a compelling sense of immersion, they produce nothing close to the powerful sense of connection to and sympathy with human subjects that old-fashioned 2D documentaries routinely engender. This video essay demonstrates and explains why.
Amuse-œil
Authors: Faden Eric
Published: March 2024

"Amuse-œil" surveys various techniques for reading films in an alternative way, what Roland Barthes calls “an interrogative reading” in his article “The Third Meaning.” The video essay then applies this technique to Jacques Tati’s Playtime (1967, France) to reveal several visual threads that are difficult or even impossible to see under normal viewing circumstances.
Of Love and Longing
Authors: Daigle Allain
Published: March 2024

“Of Love and Longing” seeks to visualize Elizabeth Freeman’s claim that “a bodily motion (a grasp, a clutch, a refusal to let go) might have something to do with knowing and making history” (Freeman xx). Editing together images from Wong Kar-Wai’s In the Mood for Love (2000), and from a trio of contemporary melodramas dealing with the queer experience of history – A Single Man (Ford, 2009), Carol (Hayes, 2015), and Moonlight (Jenkins, 2016) – it emphasizes the way that the bodily motions of touch mobilize longing in history.
Negative Space
Authors: Daigle Allain
Published: March 2024

"Haynes: Negative Space" illustrates how characters are isolated by their surroundings in Todd Haynes' films. By literalizing his frames-within-frames and manipulating negative space, I demonstrate the ways that Haynes’ films invite us to see settings as empty spaces that are antagonistic to the people who live within them.
