Development of innovative activities in the Russian Federation implicates the creation of safe and, at the same time, full-fledged in composition and consumer properties of specialized food products, as one of the main and promising tasks of the food industry. This is due to the need to provide a modern person’s diet with necessary nutrients and prevention of nutritional diseases. In this regard, development of recipes and production of functional food products using biologically active components of non-traditional plant raw materials growing in the Republic of Adygea and conducting scientific research, including the assessment of quality and biological value, are relevant. The aim of the research is to determine organoleptic, physicochemical parameters and functional properties of experimental samples of soft drinks using extracts from compositions of plant raw materials. During the course of performance phytocomposition models of mixtures of adaptogenic and antioxidant action and for the prevention of iodine deficiency have been developed, the optimal extraction option has been selected, laboratory experimental samples of functional soft drinks have been designed, quality indicators and functional properties have been investigated. The results of studying organoleptic indicators prove that the taste in all samples is quite harmonious and pleasant, with characteristic light herbal tones, the color of drinks ranges from light to rich amber, depending on the composition. The average indicator of antioxidant activity fluctuates between 156 to 244 mg/dm3. Functional food ingredients content (potassium, vitamins C, E, flavonoids and iodine trace element) of experimental samples of functional soft drinks comply with GOST R 56543-2015 Functional drinks. General technical conditions [1] are suitable for systematic consumption in order to improve physiological functions in the human body.

Published: February 2021

The article analyzes the interrelationships of the main terms and concepts used in the investigation of the regional socio-economic system stability when changing to knowledge economy, digitalization of technological processes and management. The object of the research is complex social, ecological and economic systems of a regional scale. The subject of the research is the conceptual apparatus of the research on the stability of regional systems. Key terms and elements of the conceptual apparatus, related characteristics of regional systems that determine their composition and structure, dynamic characteristics, properties have been analyzed. The statement on the applicability of the principles of self-organization to each of the components of complex regional systems has been substantiated. Distinctive features of the regional social, ecological and economic system as a complex object, such as multicomponent, subjectivity, nonlinearity, as well as the activity of elements, subsystems and the system as a whole, have been considered. A conceptual model of development of such complex self-organizing regional socio-economic systems has been presented which determines the relationship between the concepts and the basic characteristics of systems used in behavior analysis. An approach based on the use of principles of self-organization has been proposed, which allows to present the structure of interrelationships of the basic characteristics of the development of regional systems. These principles include the principle of multivariance, the principle of freedom of choice of decisions according to D. Gabor, as well as the principle of external addition, according to which the assessment of the effectiveness of the functioning of a complex system is assessed at the non-systemic level.

Authors: Fasoye Kazeem , Olayiwola Abiodun Sunday , Joseph Kehinde Elizabeth
Published: February 2021

Purpose:
This paper examined the potential of domestic industrial output on economic growth in Nigeria.
Approach/ Methodology/ Design: An Autoregressive Distributed Lag (ARDL) model procedure was employed for data analysis.
Findings: The results revealed that the contribution of the domestic industrial output to economic growth was appalling which was necessitated by the worrisome image of “Made-in-Nigeria” goods. It was also showed that the results that domestic industrial output and domestic savings have positive relationships with real gross domestic product (RGDP) in the long run. This implies that a rise in the level of each of domestic output and domestic savings necessitated an increase in real gross domestic product (RGDP).
Practical Implication: The implication presented in this study is related to the concerned authorities. The results indicate the need for diverse domestic production in order to achieve a healthy competition in the industrial sector in the country.
Originality/Value: The study innovates by employing various statistical tools for exploring the effect of domestic industrial output on economic growth. The significant contribution of this study is in identifying that domestic production in Nigeria has been lagged behind in terms of output performance in the economy.

Authors: Khan Bhola
Published: February 2021

Purpose: In this article attempt is made to develop a composite food security index for some selected countries of the Economic Community of West-African States (ECOWAS), e.g. Nigeria, Niger, Benin, and Ghana. The study also aims to study the stability property of the indicators of composite food security index.
Approach/ Methodology/ Design: For constructing a composite food security index for ECOWAS, one can use the basic methodology already developed by IFAD but in a modified form. This study is also based on IFAD methodology but with one more additional variable that is political stability index and assigned weight on the basis of Principal Component Analysis (PCA).
Findings: This composite index is an improvement over all the other food security index developed by others eminent economists and institutions from time to time. This index consists of six indicators such as food availability, food production, self-sufficiency of food, inverse relative price index, child survival index, and political stability to construct the composite food security index of ECOWAS. Political stability is an additional indicator in the index of ECOWAS. With the help of this index, the trends, stability and situation of food security index in region are discussed and analyzed from 2001 to 2018.After careful analysis of composite food security index of ECOWAS, one can find out that It has quite impressive and improving gradually.
Practical Implication: This study provides strong suggestion about how these five indicators of composite food security index provide an overview for the selected countries to secure their level of food security in their respective country.
Originality/Value:  After the careful analysis of the collected data, it can be concluded that the composite food security index plays an important role to understand whether food security index is improving in respective countries or not.

In today's intense competition environment, enterprises must use their production resources effectively in order to sustain their assets. The importance of this issue is increasing day by day. For this reason, enterprises are working to manage their resources in the best way with various methods. One of the most important sources for businesses is labor. It is necessary to make effective use of human factor in labor intensive enterprises. In addition, absence in the business is very common. In this study, a mathematical model was firstly proposed in order to assign the appropriate personnel instead of daily absentee staff in an automotive supplier industry and to distribute the work if necessary; afterwards, in order to answer the needs of the enterprise, the Decision Support System (DSS) has been designed. In the event that the personnel does not come to work in the operation with the proposed DSS, the most authorized personnel is assigned to the relevant work stations and the work is shared to the other stations where necessary. Therefore, with a systematic process management, sustaining of standard production and minimizing the losses which may occur are aimed.

Teatro para el tratamiento de la discriminación étnica y la xenofobia en jóvenes ecuatorianos
Authors: Jiménez Sánchez Álvaro , Vayas Ruiz Eliza Carolina , Paredes Ruiz Teresa
Published: February 2021

La inmigración a tierras ecuatorianas en los últimos años ha provocado un lamentable aumento de la xenofobia. Asimismo, el país andino siempre se ha caracterizado por la convivencia entre la población mestiza y los diversos grupos étnicos, especialmente los indígenas, aunque en ocasiones también se han dado casos de discriminación contra el último colectivo por parte de los mestizos. La comunicación en salud es uno de los múltiples enfoques para abordar este tipo de violencia y en concreto aquellas estrategias que utilizan el drama para concienciar sobre estos aspectos. Este estudio analiza el desarrollo de un taller universitario de teatro social realizado durante tres semestres con 50 estudiantes con el propósito de abordar temas como la xenofobia y la discriminación étnica entre jóvenes y adolescentes. Como resultado se obtuvieron diversas escenas y dinámicas dramáticas efectivas para la reducción de los temas tratados. Se concluye que estas estrategias teatrales pueden servir de referencia en otros contextos y bajo enfoques metodológicos similares a la hora de recurrir al entretenimiento, el arte y la educación como una forma más de concienciar y sensibilizar hacia este tipo de violencia.
El modelo de la alternancia y la desigualdad educativa territorial en la educación en Colombia
Authors: Herrera Monsalve Doris Yaneth
Published: February 2021

Este artículo pretende evidenciar la desigualdad educativa territorial que existe en Colombia, en especial, en el marco de la coyuntura de la emergencia sanitaria nacional por causa del coronavirus COVID-19, declarada mediante resolución 385 del 12 de marzo de 2020 por el Ministerio de Salud y Protección Social y de conformidad a lo manifestado en la circular 20 del Ministerio de Educación Nacional, por tanto, se pretende problematizar el “modelo de alternancia” propuesto por el gobierno nacional. Este artículo pretende abrir opciones para repensar a los sujetos que van a la escuela -estudiantes y docentes- como lo plantea Southwell (2014): “los múltiples modos en que los sujetos enseñantes asumen, viven y piensan su tarea, y los problemas, desafíos y utópicas que se plantean en torno de ella” (p. 166).
 
Por tanto, el modelo de la alternancia presenta la posibilidad de una relación multidimensional, y se espera que este texto sea un disparador para conversaciones entre los hacedores de la política pública y los sujetos que asisten a las instituciones educativas como una oportunidad para debatir y comprender “el orden social” (Ranciére, 2018).
 
En suma, la ruta de este articulo plantea un interrogante para abrir diálogos en el sistema educativo del centro y la periferia ¿Cuáles son esos artefactos que posibilitaran traspase de la sinrazón no igualitaria?, en términos de Ranciére (2018): “el amor a la dominación obliga a los hombres a protegerse unos de otros, en el seno de un orden convencional que no puede ser razonable porque no está hecho más que de la sinrazón de cada uno” (p.  134).
 
El texto se organizó en dos grandes apartados. El primero de ellos, busca hacer una presentación somera que describe y ubica geográficamente a dos municipios en Colombia- Bogotá y Arauca-, al parecer muy disimiles por la extensión y la ubicación geográfica que aplican los mismos indicadores que da cuenta de los discursos hegemónicos que han estado presente en el continente latinoamericano y que han socavado la libertad en términos de Ranciére (2018): “es más cómo compararse, establecer el intercambio social como ese truque de gloria y desprecio en donde cada uno recibe superioridad en contrapartida de la inferioridad que confiesa. Así la igualdad entre seres razonables vacila en la desigualdad social” (p. 134). En un segundo apartado, se plantea que la alternancia plantea una medida desde una mirada univoca perdiendo de perspectiva la riqueza que da el entramado social del sistema de educación en Colombia y pone sobre la mesa una oportunidad para abrir mundos y caminos distintos para cumplir con la permanencia escolar y establece un desafío para familias, docentes, niños y jóvenes en la ampliación de estrategias en clave de la concepción de la justicia  como un asunto ético de la sociedad colombiana que no pierda de vista la educabilidad capaz de producir desarrollos según las características singulares de los sujetos (Martinis, 2016).

Published: February 2021

Hasta el año 2020, los cambios a la hora de educar en la práctica solían producirse de forma paulatina y concreta en los distintos niveles educativos. En el nivel inicial, la inclusión de tecnologías en muchas oportunidades generó resistencias. En la actualidad, sabemos que es necesario repensar las bases teóricas y las prácticas que hacen referencia a la educación ya que se han produciendo cambios importantes y vertiginosos en el contexto de cuarentena obligatoria generado por el COVID- 19. Realizaremos un análisis de casos de propuestas educativas generadas y desarrolladas por tres instituciones de nivel inicial de Argentina (Ciudad Autónoma de Buenos Aires y ciudad de Ezeiza) y España (Madrid) en donde se reflejan dichos cambios abruptos. Relacionaremos estos casos con autores clave en campos tales como la Didáctica del Nivel Inicial y la Tecnología Educativa.
Driving mechanisms of organic carbon burial in the Early Cretaceous South Atlantic Cape Basin (DSDP Site 361)

Published: February 2021

Abstract. Extensive black shale deposits formed in the Early
Cretaceous South Atlantic, supporting the notion that this emerging ocean
basin was a globally important site of organic carbon burial. The magnitude
of organic carbon burial in marine basins is known to be controlled by
various tectonic, oceanographic, hydrological, and climatic processes acting
on different temporal and spatial scales, the nature and relative importance
of which are poorly understood for the young South Atlantic. Here we present
new bulk and molecular geochemical data from an Aptian–Albian sediment
record recovered from the deep Cape Basin at Deep Sea Drilling Project
(DSDP) Site 361, which we combine with general circulation model results to
identify driving mechanisms of organic carbon burial. A multimillion-year
decrease (i.e., Early Aptian–Albian) in organic carbon burial, reflected in
a lithological succession of black shale, gray shale, and red beds, was
caused by increasing bottom water oxygenation due to abating hydrographic
restriction via South Atlantic–Southern Ocean gateways. These results
emphasize basin evolution and ocean gateway development as a decisive
primary control on enhanced organic carbon preservation in the Cape Basin at
geological timescales (> 1 Myr). The Early Aptian black shale
sequence comprises alternations of shales with high (> 6 %) and
relatively low (∼ 3.5 %) organic carbon content of marine
sources, the former being deposited during the global Oceanic Anoxic Event
(OAE) 1a, as well as during repetitive intervals before and after OAE 1a. In
all cases, these short-term intervals of enhanced organic carbon burial
coincided with strong influxes of sediments derived from the proximal
African continent, indicating closely coupled climate–land–ocean
interactions. Supported by our model results, we show that fluctuations in
weathering-derived nutrient input from the southern African continent,
linked to changes in orbitally driven humidity and aridity, were the underlying
drivers of repetitive episodes of enhanced organic carbon burial in the deep
Cape Basin. These results suggest that deep marine environments of emerging
ocean basins responded sensitively and directly to short-term fluctuations
in riverine nutrient fluxes. We explain this relationship using the lack of
wide and mature continental shelf seas that could have acted as a barrier or
filter for nutrient transfer from the continent into the deep ocean.
Rankings of extreme and widespread dry and wet events in the Iberian Peninsula between 1901 and 2016

Published: February 2021

Abstract. Extensive, long-standing dry and wet episodes are two of
the most frequent climatic extreme events in the Iberian Peninsula. Here, a
method for ranking regional extremes of persistent, widespread drought and
wet events is presented, considering different timescales. The method is
based on the multi-scalar Standardized Precipitation Evapotranspiration Index
(SPEI) gridded dataset for the Iberian Peninsula. Climatic Research Unit
(CRU) data are used to compute the SPEI between 1901 and 2016 by means of a
log-logistic probability distribution function. The potential
evapotranspiration (PET) is computed using the Penman–Monteith equation.
The ranking classification method is based on the assessment of the
magnitude of an event, which is obtained after considering both the area affected by the respective dryness or wetness – defined by SPEI values over a
certain threshold – and its intensity in each grid point. A sensitivity
analysis of the impact of different thresholds used to define dry and wet events
is also performed. For both the dry and wet periods, this simple yet robust tool
allows for the identification and ranking of well-known regional extremes of persistent,
extensive dry and wet periods at different timescales. A comprehensive
dataset of rankings of the most extreme, prolonged, widespread dry and wet
periods in the Iberian Peninsula is presented for aggregated timescales of
6, 12, 18, and 24 months. Results show that no region in the Iberian Peninsula is more prone to the occurrence of any of these long-term (dry
and/or wet) extreme events. Finally, it is highlighted that the
application of this methodology to other domains and periods represents an
important tool for extensive, long-standing, extreme event assessment
worldwide.
The Antecedents and Challenges of Innovation in Sustainable Development Projects: Systematic Review
Authors: Hassan Afaf
Published: February 2021

This study demonstrates the antecedents and challenges of innovation in sustainable development (SD) projects. In particular, a systematic literature review is conducted to highlight the challenges of innovation, that can suppress the efficient attainment of innovation benefits, in SD projects. The findings indicate that the positive benefits of innovation, in SD projects, are applying new strategies, developing new management practices, increasing interests and commitments of project team members, obtaining a better quality, attaining competitive advantages, introducing active influencers, establishing more engagement and collaborative work among team members, and satisfying project stakeholders. On the other side, innovation challenges that could act as barriers to achieve these benefits, in SD projects, are innovation resistance, stakeholders’ requirements, pressure from clients to meet the SD project goals, diverse project environment, dynamic and unstable markets, project structure and characteristics, compliance with the common goals between innovation and sustainable development projects, and less management support and commitment for innovation. In brief, if project team members could overcome these challenges, innovation could be adopted and implemented effectively in sustainable development projects.

Published: February 2021

Selected eight inbreed line were used in crossing as half diallel fashion to find out different genetic parameter as well as targeting superior combination for hybrid vigour. Sunflower first introduce in Bangladesh 1980 by Bangladesh Agricultural Research Institute and Mennonite Central Committee. BARI Sunflower-1(Kironi) and BARI Sunflower-2 is only two released variety. But major obstacles for sunflower cultivation are both varieties are more than 1.50m height and require > 100 days for maturity. As this country is facing climate change unfavorable weather, sunflower cannot withstand in stormy weather. Specially at the time of prematurity stormy weather causes lodging due to over height, it is essential to develop dwarf stature plant.  Due to strong crop competition in winter it cannot fit in major cropping pattern T-Aman-Mustard-Boro due to it long duration. Bangladesh has accessible land of 0.85 million hectares in saline areas (Banik et al., 2011). These lands can be used for sunflower cultivation as it is moderately saline tolerant (Rahman et. al. 2018). On the other hand in different part of Bangladesh (e.g. Cumilla, Manikgonj, Sherpur, Jamalpur, Netrokina, Tangail, Dinajpur, etc.), a huge amount of lands are kept fellow after T. Aman harvest. These current fellow lands can be easily used by sunflower cultivation if short duration varieties are available. Both plant height and days to maturity were considered as favorable for negative heterosis to obtain dwarf plant stature and short duration plant to fit in existing cropping pattern in Bangladesh. Positive heterosis is considered desirable for other yield contributing traits. The hybrid HE15, HE17 and HE16 showed significant negative heterosis both for mid parent and better parent. Negative heterosis for plant height is desirable to adopt hybrid in unfavorable weather condition. The Hybrid HE15 showed both for significant negative mid parent and better parent heterosis. High heritability along with significant mid parent and better parent heterosis indicate scope of utilization of hybrid as commercial and further use in breeding programmes. Several outstanding cross combinations, HE17, HE16, HE14, HE15, and HE18 showed significant and desirable heterosis for seed yield per plant over mid parent and better parent. The hybrid combinations HE17, HE16 and HE14 could be utilized to exploit the heterosis as well as commercial multiplication of seed to get direct benefit by the farmers.
Relationships Between A and B/A2 Horizons of Three Soils in the Context of Viticulture
Authors: Alba José Maria Filippini , Flores Carlos Alberto , Miele Alberto
Published: February 2021

The purpose of this study was a comparison of soil parameters among superficial and sub-superficial horizons of three representative type of soils in Vale dos Vinhedos, Brazil, aiming Viticulture in general, but Precision Viticulture (PV) management as specific focus. Basic aspects of Viticulture or PV are still discussed, by instance, sampling procedures, influence of pedology on quality of wine or methods for defining the management zones. Samples were collected according to each horizon, superficial (0-20 cm in depth) or sub-superficial (>40 cm in depth), that is, A (all soils), A2 (Neossolo), Bi (Cambissolo), or Bt (Argissolo). Micro-vinification was performed for grapes derived from five classes of soil. The pedological parameters analyzed were granulometric fractions, chemical parameters and degree of flocculation. Data were organized according to a Geographic Information System (GIS) by ten classes of soil. Basic statistical analysis, line graphs, XY plots and factor analysis were used to interpret the physicochemical variables related to horizons, soil and wine. Relative Accumulation Indexes were evaluated for horizons of soil, classes of soil and wine. Data organized by horizon and type of soil showed great dispersion, so outliers were discarded and data organized by class of soil. Correlation of data related to soil horizons, A against A2/B, was evident for macronutrients. Micro-vinification altered content of K and P in wine. Relative Accumulation Indexes of soil horizons correlated to declivity, when declivity lesser than 20% occurred. Fe and Zn showed correlation among sub-superficial horizon and wine for some classes of soil.

The inclusion of natural extracts and solution of synthetic astaxanthin in the Macrobrachium amazonicum diet were tested to verify their effect on performance, body indexes and total accumulation of astaxanthin in the reproductive tissues and gametes of this crustacean in comparison with newly captured wild animals. The experiment was randomized in blocks (five treatments with three replicates). Four groups were submitted, during 20 days, to diets in recirculation tanks: control diet (CONT); diet containing natural extract of “buriti” (CAR); diet with inclusion of natural “urucum” extract (BIXN), diet with synthetic astaxanthin (ASTX) and NATURAL group (not fed with ration). 180 prawns were used, with 60 males (6.08±1.96 g) and 120 females (4.55±1.03 g) distributed in five groups containing four males and eight females each. There were no significant differences in performance and body indexes. The number of released spermatozoids, live spermatozoids, body and egg pigmentation was higher in BIXN and ASTX treatments. The ASTX treatment was superior to the NATURAL group in the body pigmentation of females and eggs and release of spermatophores by males. These results demonstrate that the use of natural and artificial carotenoid pigments in the diet are beneficial for reproduction of M. amazonicum.

Size distribution, length-weight relationship and condition index are some of the many parameters that contribute to the study of the growth, environmental conditions and reproduction of an aquatic species. For Tagelus adansonii, only a few studies were carried out on these parameters. This species is a bivalve of the solecurtidae family only found on the East Atlantic Coast between Mauritania and Angola. The objective of this study was to examine the biometric relationships as well as size and condition index variations, within the perspective of resource management. In this study, the average size obtained (47.78mm) from the monthly sampling in Joal Fadiouth lagoon was smaller compared to sizes obtained in other countries for the same genus and species. The size frequency distribution is unimodal, the most abundant class is 45-50mm. The mean condition index is 18.41±16.47 using the formula by Beninger and Lucas (1984). The values of the condition indices varied throughout the duration of the study. In the period of cold-to-warm transition (June) the maximum values of the condition indices were observed, while in the period of warm-to-cold transition (November to December), the minimum values were registered. The allometry is positive (3.07) in Joal as in most studies on this genus.

The development of social skills (SS) at various stages of life provides the basis for social and academic success throughout life. This cross-sectional study validates and verifies the reliability of the SS checklist proposed by Goldstein et al 1983. The checklist was administered, which is composed of 6 dimensions and 50 SS questions. 671 students between 18 and 25 years of age, belonging to eight professional programs in the area of Educational Sciences, participated. The results showed that five factors explained 41.4% of the variance of the instrument. The Kaiser-Meyer-Olkin KMO measure of 0.906 and Bartlett's test of sphericity were highly significant (X2= 11020.251, gl= 1225). The factor loadings of the 6 dimensions and the 50 questions ranged between 0.42 and 0.72. The reliability achieved by Cronbach's alpha was r=0.92. The proposal of percentiles will allow classifying low, moderate and high levels of SS, providing information that can be used not only by students, but also for professionals working in higher education. Consequently, it highlights the importance of developing SS not only at home, but also at school and university, since they need to be stimulated at every stage of life to achieve the proposed objectives.

Nursing higher education mergers: Do the benefits outweigh the risks?
Authors: Avadhani Amita
Published: February 2021

Merger as an organizational change has the potential to create turmoil, unrest, and uncertainty among the employees. Despite the shortage of nursing education workforce, global economic hardships have brought on a recent increase in nursing higher education mergers. The focus on integrated operations of the newly merged organization can burden all involved. Financial and business survival factors can create an unintentional oversight of the employee feelings. Nursing education faculty and administrator’s quality of work lives are related to their performance, which ultimately determines organizational performance. The purpose of this qualitative case study was to evaluate the influence of a nursing higher education merger on the quality of work lives of faculty and administrators. Principal results of this research revealed that faculty and administrators perceived the influence of the nursing higher education merger to be negative in the beginning with a transition to a positive influence over 5 years. Challenges in this merger were related to cultural integration and the magnitude of work required for operationalization. Exact timing of transition of the negative influence to positive was not established and needs further research. These results have implications on the nursing higher education institutions planning future mergers. Nursing education leaders must utilize strategies to address the quality of work life factors during the nursing higher education mergers. Implications of maintaining quality of work lives during an organizational change has the potential to address the nursing and nursing education workforce issues.

Background and aim: Authentic leadership is relatively a new paradigm that emphasizes leaders' credibility. It can serve the healthcare organization to build an organizational culture that reinforces the healthcare worker in being committed and engaged in work. This study aimed to examine the effect of authentic leadership on staff nurses' affective organizational commitment and work engagement through examining the mediating role of behavioral integrity.Methods: Study design: A descriptive correlational design was used in conducting this study. Setting: The study was conducted at two different hospitals, namely Menoufia University Hospital, and National Liver Institution, Egypt. Sampling: A Convenience sampling of two groups were selected; 64 front-line nurse managers and 320 staff nurses. Tools: Four instruments were used for collecting data; authentic leadership questionnaire, behavioral integrity scale, affective organizational commitment questionnaire, and Utrecht work engagement scale. Spearman correlation (r) and binary logistic regression analysis were used to achieve the study aim.Results: Total behavioral integrity (BI) score was significantly correlated with total authentic leadership (AL) and two of its subscales (internalized moral perspective and balanced processing). Moreover, a significant positive correlation was revealed between the enactment of espoused values at one hand and total authentic leadership and its subscales except for self-awareness. Correlation analysis between BI and organizational commitment revealed a significant positive correlation between the two variables. A significant positive correlation was also found between the BI total and its subscales with work engagement total and its subscales.Conclusions: This study supported the proposition that the relationship between authentic leadership and positive nurses’ outcomes including affective commitment and work engagement is mediated by behavioral integrity.

This research sought to examine the curriculum planning/implementation processes involved in the public ECCE sector in a Caribbean country. One of the focal areas was the involvement and contributions by stakeholders with respect to ECCE curriculum at public ECCE centres. In order the capture data on this area, a qualitative approach was adopted. Two (2) focus group sessions with a total of twenty (20) parents were conducted at seven (7) public ECCE centres. The study yielded compelling evidence that there was limited parental involvement as it relates to curriculum and little to no awareness of the curriculum being implemented at their children’s ECCE centres. Recommendations were proffered in the form of an intensive stakeholder inclusion programme containing a myriad of strategies targeting the inclusion of parents.

Modern studies show that children and adolescents represent the population of users who spend the most time online and that are significantly more exposed to risk behaviors, mostly in cyberbullying. Therefore, the aim of this paper is to determine the effectiveness and frequency of using restrictive strategies in parental control over a child's online activities. The survey sample contains 183 first and fourth grade high school students answering questions about parental monitoring and cyberbullying. Parental monitoring was examined by a short questionnaire consisted of several categorical questions, while the Cyber Victim and Bullying Scale was used to examine cyberbullying. The results of this study show that parents infrequently use restrictive strategies in monitoring child's internet use. Parents use their strategies mostly to avoid child's chatting with strangers (51.9%) and leaving personal information on the Internet (35.5%), while certain parents have a password of the devices that child uses to access the Internet (37.2%). Only one in five parents limit access to certain websites, while one in ten limit amount of time their teen can go online. The final analysis showed that there is no statistically significant association of restrictive strategies in parental control and digital violence. Parental control can become a significant role in preventing and reducing digital violence in adolescents, but it is necessary to direct parents to make decisions about online rules of conduct in agreement with children and in accordance with their activities and encourage them to use other, adequate parental control strategies.
