Authors: ÇİL Serdar
Published: October 2023

Dünya genelinde giderek yaygınlığını artırarak gerek kullanıcıların gerekse reklamverenlerin ilgisini çeken podcast yayıncılığı, Türkiye’de pandemi döneminde başlayan yükselişini sürdüremediği gibi bir gerileme sürecine girmiştir. Podcast yayıncılığının tanıtılamaması, podcast dinleyicilerinin beklentilerinin anlaşılamaması, yapımcıların süreklilik arz eden bir maddi gelir elde edememesi ve buna bağlı olarak içerik üreticilerin amatör düzeyde kalması ve yapımların periyodik olmaması bu gerilemenin sebeplerinden sayılabilir. Bu sorunlar çerçevesinde araştırmanın temel amacı Türkiye’deki podcast dinleyicilerinin profillerini, içerik kullanım yöntemlerini ve tüketim motivasyonlarını ortaya koymaktır. Bu doğrultuda uygulanan anket çalışmasında, podcast dinleyicilerinin genç, eğitimli ve orta-üst sosyo- ekonomik sınıftan oldukları görülmüştür. Podcast kullanıcıları genellikle geleneksel medyada göremedikleri toplum ve kültür, eğitim, bilim ve sanat konularına yönelik içerikleri takip etmektedirler. Kullanıcıların içerikleri ağırlıklı olarak cep telefonlarından ve evde dinledikleri görülmüştür. Ayrıca kullanıcılar içerikleri tüketirken başka işlerle uğraşmayı tercih etmektedirler. Podcast kullanıcılarının içerik tüketim motivasyonlarına bakıldığında ise (a) teknik açıdan işitsel platform üstünlüğü (b) kişisel-toplumsal özdeşleşme, arkadaşlık, ilişki kurma (c) kaçış ve zaman geçirme motivasyonları ön plana çıkmaktadır. Bu motivasyonlar cinsiyete, yaşa ve eğitim durumuna göre farklılaşmaktadır. Erkek kullanıcıların tüketim motivasyonları kadınlara göre daha yüksektir. Gençlerde ise içerik açısından işitsel platform üstünlüğü öne çıkan motivasyon olarak görülmektedir. Ayrıca eğitim düzeyi geriledikçe kaçış ve zaman geçirme motivasyonu, eğitim düzeyi arttıkça kişisel-toplumsal özdeşleşme, arkadaşlık, ilişki kurma motivasyonu öne çıkmaktadır.
The effect of social media addiction on communication skills: A meta-analysis study
Authors: POLAT Hıdır
Published: October 2023

The growing prevalence of digital tools in our daily lives exposes us to various forms of addiction. The rise in social media usage places social media addiction at the forefront of concerns. Numerous studies exist on the impact of this addiction on individuals' lives. The impact of social media on individuals' communication skills is an important research area due to its effective use in the communication process. Studies investigating the impact of social media addiction on communication skills have found different results. This study aims to evaluate the overall impact of social media addiction on communication skills. In this direction, a meta-analysis was conducted on 16 studies dealing with the relationship between social media addiction and communication skills. CMA software was used in all analyses. The results show that social media addiction has a moderate negative effect on communication skills. The average effect was tested in the context of moderator variables. Accordingly, the average effect does not show a significant difference according to disciplines, while it shows a significant difference according to countries. The study suggests an explanation for developing further research and protecting communication skills from the negative effects of social media.

Published: October 2023

This study aims to determine the effectiveness of different doses of vitamin E on the maturation of freshwater crayfish (Cherax quadricarinatus). The method used was a Randomized Block Design (RAK) with 4 treatments and 3 replications. The treatments in this study were P1 (control), P2 (vitamin E 150 mg/kg feed), P3 (vitamin E 300 mg/kg feed), and P4 (vitamin E 450 mg/kg feed). Parameters observed in this study were Gonad Maturity Index (GIC), fecundity, and egg diameter. The results of Duncan's analysis showed that the increasing vitamin E to feed was significantly different (P<0.05) with treatment without increasing vitamin E to LAT maturation such as gonadal maturity index, fecundity, and egg diameter. However, administering different doses of vitamin E (150 mg/kg of feed, 300 mg/kg of feed, and 450 mg/kg of feed) had no significant effect on LAT maturation. The treatment without the increasing vitamin E did not show maturity, which was indicated by the value of all parameters 0, while the treatment with the increasing vitamin E to the feed resulted in a range of IKG values, fecundity, and egg diameter respectively was 8.28 - 9.84%, 230.66 - 30.66 eggs and 0.46 – 0.48 mm. The best treatment in this study was treatment with a dose of vitamin E 450 mg/kg feed because it had the highest reproductive performance and could accelerate gonadal maturity in LAT.Keywords: Egg Diameter; Fecundity; Freshwater Lobster; Maturation; Vitamin E

Authors: Aryansyah Akbar , Anggoro Sutrisno , Afiati Norma
Published: October 2023

Osmoregulation is a physiological adjustment mechanism of fish to environmental conditions. Fish growth performance will reduce when a large amount of energy is redirected for the osmoregulation process. The purpose of this study was to determine the osmotic work level (OWL), osmoregulation pattern, condition factor (K), gonad maturity stages (GMS) and analyze the relationship between OWL with condition factor and GMS of tilapia collected from three floating net cages in Cengklik reservoir, Boyolali. Samples were collected during March – April 2022 followed by some allometric measurements and regression analyses. The OWL of tilapia at the three cages ranged from 4 – 10 mOsm/L H2O; they performed a hyperosmotic osmoregulation pattern. The condition factor of male and female tilapia were1,86±0,21 and 1,89±0,18. GMS of both male and female tilapia was dominated by GMS IV with a fecundity of 9408±2092.54 eggs. OWL did not reveal a significant effect on condition factors or on the GMS of tilapia (p>0.05). Pearson correlation test showed a weak relationship between OWL with condition factors (r = 0,204) and tilapia GMS (r = -0,001). Therefore, tilapia uses less energy in osmotic work to produce good growth performance because it has more energy for growth, as indicated by the high condition factor (K>1) and domination by fish with GMS IV level of mature gonads.Keywords: Condition Factor; Gonad Maturity; Fish Cages; Oreochromis niloticus; Osmoregulation

LAS (Linear Alkylbenzene Sulfonate) surfactants are the main cleaning agents from the anionic group found in detergents that are widely used in Indonesia. LAS decomposes in surface water for 1-2 days, in sediments it decomposes for 1-3 days, in marine and estuarine systems it decomposes for 5-10 days. LAS is generally degraded by as much as 90% within 3 months, with a time ranging from 5-30 days (World Health Organization, 1996). LAS surfactants can cause damage to the gill epithelium and blockage of branchiola channels in fish. This study aims to determine the toxic effect of LAS surfactant on the survival of white snapper (Lates calcarifer) fry and to determine the toxicity value of LC50 (Lethal Concentration) of LAS surfactant to white snapper (Lates calcarifer) fry on a laboratory scale.

One of the recognised main requirements determining the efficacy of a pesticide formulation is its stability in storage. The different pesticides have to be procured well in advance and kept in sufficient stocks by dealers as well as by the farmers to meet the demands for plant protection operations during the proper time and season of the crops. There is no adequate information at present on the shelf life (stability) of the different pesticide formulations during storage apart from the claims of the manu- facturing firms in respect of the stability of the basic technical materials used in the pesticide formulations. At the Pesticides Testing Laboratory, Coimbatore, deterioration was reported in active ingredients in some pesticide formulations (Thyagarajan and Venkataraman, 1967). Studies were continued in the Pesticides Testing Laboratory, Coimbatore on this aspect with some more pesticide formulations received for tests at the laboratory, adopting the usual methods of storage of pesticides purchased in the Agricultural Depots and the results are presented below.

Fungicidal Control of Tikka Leaf Spot' of Groundnut in Tamil Nadu
Authors:   Assitant Plant Pathologist, Regional Agricultural Research Station Tindivanam, H.D LEWIN , S NATARAJAN ,   Assitant Plant Pathology, Regional Agricultural Research Station Tindivanam
Published: October 2023

Groundnut which is one of the most important oilseed crops is susceptible to some of the most serious diseases like 'tikka'-Cercospora personata (Berk. & Curt.) Ell, & Eve., Cercospora arachidicola Hori, and Root rot-Rhizoctonia bataticola (Taub.) Butl. The low yield of pods in India is to a great extent attributed to some of these diseases as well as pests. Reduction in yield from 20 to 50% due to severe cases of tikka alone has been reported from Uttar Pradesh by Mehta et al. (1954). Similarly Sulaiman (1965) has recorded a loss in yield upto 40% in the Maharashtra State. Reduction in yield is largely due to the damage caused to the leaves as a result of intense spotting and the consequent loss in photo-synthetic tissue; 35% of the leaf area has been reported to be lost in parts of North America (Wolf, 1916). Spots on the pegs also tend to decrease yield by restricting translocation of food to the seeds (Reys et al., 1940). Premature leaf fall, which is invariably associated with tikka incidence, is also a factor contributing to the low yield of groundnut.

osette disease of groundnut was first reported in Tanganyika territory by Zimmerman in 1907. Sundararaman (1926) reported the occur- rence of a virus disease of groundnut at Palur Agricultural Experimental Station, Madras State. He named it as clump disease'. Storey and Bottomley (1928) concluded that the 'clump disease' reported by Sundara- raman (1926) in Madras State was similar to rosette disease of South Africa. Rosette disease is one of the virus diseases affecting groundnut crop in Tamil Nadu. The incidence of the disease varies from 0-25 0%. A scheme was initiated at the Agricultural College and Research Institute, Coimbatore with the financial assistance of The Indian Central Oilseeds Committee and later of the Indian Council of Agricultural Research to study the various aspects of the virus diseases occurring in groundnut crop.

Adaptive Research studies are currently being undertaken by the extension personnel. Correct understanding and appreciation of this termino- logy is necessary to know exactly what needs to be accomplished in the field. Specifically stated, it is a field testing programme of a scientific finding for immediate application before recommending for mass scale adoption. 'Field Testing, 'Field Verification trials', 'On-the-farm Testing' are some of the terms used to denote adaptive research. Adaptive research studies have assumed added importance in the context of voluminous flow of scientific findings from different research centres within the country and outside. Consequently, the extension worker has perforce to understand clearly whether or not a particular scientific recommendation will be suitable to his area and capable of meeting the needs and demands of the farmers and solving the local agricultural problems.
Standardization of Soil Sampling Method in Arecanut. Part I: Variation in Fertility Gradient under Basin System of Manuring
Authors:   Senior Research Assitant and Soil Chemistry, N.T BHAT , A.R MOHAPATRA ,   Central Research Institute of Plantation Crop Vittal
Published: October 2023

Basin system of manuring is a common practice in recanut cultivation. Shallow basins with a radius of about three-fourths of meter are opened around the base of palms where green leaf, manure and ertilizers are applied and covered with thin layer of earth. Since the usual spacing adepted for arecanut is 2.7 m x 2.7 m, there remains large area in between the palms which does not receive any fertilizer or manure. The problem of soil sampling in such a case would differ from that adopted for annual crops. The present investigation was undertaken to study the differences if any. existing in the fertility level of soil samples collected from the basins at three lateral distances from the base of the palm and at two vertical depths for each of these lateral distances with the object of fixing suitable soil sampling technique for arecanut.

Among the root-knot nematodes, Meloidogyne arenaria (Neal, 1889) Chitwood, 1949 is commonly prevalent in the chilli growing tracts of Tamilnadu. Recent studies carried out by Rajagopalan and Seshadri (1969) have proved the pathogenic effect of this nematode on chillies Capsicum aiinum variety Sithur samba, Rajagopalan et. al. (1969) have observed that of the three species, M. incognita (Kofoid & White, 1919) Chitwood, 1949 M. javanica (Treub, 1885) Chitwood, 1949 and M. arenaria (Neal, 1889) Chitwood; 1949 the last one is more harmful to the chilli variety Sathur samba of Capsicum annum. No investigations have ever been made to select any resistance variety of chilli against the root-knot nematode infection except stray and causal observations made by Hare (1956). Therefore, the authors have made preliminary screening of as many as nineteen varieties of chillies against M. arenaria and the results of the observations are presented in this paper.

The main superiority of dwarf high yielding varieties of wheat lies in higher response per unit nutrient giving nearly two to three times more response as compared with local varieties. Little work has been done on two aspects of manuring of high yielding varieties, i.e., how much and at what stage of plant growth the fertilizers should be applied in different agro-climatic regions.

The dagger namatodes (Xiphinema spp.) and the needle nematodes. (Longidorus spp.) are two important groups of phytoparasitic nematodes in Dorylaimida. They not only cause root injuries but also act as vectors of some important virus diseases. Although these genera are known to be widespread, nothing was known about them in India, till Siddiqi reported their occurrence in 1959. In a survey conducted to know the occurrence and distribution of various species Xiphinema and Longidorus in Tamil Nadu four species of Xiphinema, viz. X americanum, X. basiri, X. elongatum and X. insigne and two of Longidorus, L. elongatus and L. sylphus were found to be very common in the soils in and around Coimbatore. A short morpho- logical description, range of measurements and the associated host plants, many of then are new hosts, hitherto not recorded for these genera are presented in this paper. The various species have been collected mainly from Coimbatore region except otherwise stated.
Control of the Potato Golden Nematode (Heterodera rostochiensis Woll): Campaign on the Nilgiris
Authors:   Project Officer Indo-German Nilgiris Development Project Nilgiris, A.R BHASKARAN
Published: October 2023

Discovered in 1961 on the Nilgiris for the first time in India. Heterodera rostochiensis has been a very serious pest, known popularly as "Golden Nematode of potatoes". Repeated surveys were made to locate and keep track of the spread of this infection in the potato fields and the current estimate of the affected area is 3050 acres which is approximately 15% of the total area cultivated under potato in the Nilgiris. On the Nilgiris the Golden Nematode appears to have been introduced along with seed imports in the past (Seshadri and Sivakumar 1962). Its multi- plication and spread is found encouraged by the prevalence of mono-cropping of potatoes year after year and the conducive climate. Infestation at the level of 50 Cysts per 100 mille-litre of soil has been known to affect crop performance and reduce yields. Infection at higher than 300 cysts per 100 mille-litre is observed to very severely affect the yield. Often at this level of infestation, farmers fail to harvest a crop. Symptoms of nematode infestation include an unthrifty stand, (in the initial stage), yellowing in patches, similar to N defici- encies, and dying out of whole plants. Symptoms may manifest on an entire field, or in parts of it, depending upon the distribution of the nematode popula- tion in the area.
A New Interspecific Hybrid in the Genus Arachis.

Published: October 2023

Interspecific crosses in the genus Arachis have been reported by several workers. The earliest cross appears to have been made between A. rasteiro and Holland Jumbo (Ann. Rep. 1947). A.hypogaea and A. villosa have been successfully crossed by Krapovickas and Rigoni (1951), D' Cruz (1956), and Raman (1959). Other interspecific crosses involving A.hypogaea, A. monticola and other wild species, not named then, have also been reported by Raman (1958, 1959 a, b, c, 1960). John et al (1954) reported to have made several successful crosses among three species, viz. A. rasteiro, A. nambyquarae and A. hypogaea.

Ranganathan et al. (1964) reported that the addition of phosphate and potash both in low and high doses neither increased the yield nor improved the juice quality of sugarcane in the Nellikuppam factory zone. In this experiment phosphate was added as super to soil at planting. Since phosphates applied to soil in such a soluble form get more or less fixed up it is not unlikely that the a absence of response to phosphates in the experiment is to some extent atleast caused by such fixation, which makes phosphate non- available in adequate quantity. Response to phosphates should therefore, be tested under conditions which do not favour soil fixation before the utility of phosphate fertilisers to sugarcane in the tract is finally settled. Accordingly, an experiment with different phosphate carriers was conducted in the Sugarcane Research Station, Cuddalore for three years and results obtained are presented and discussed in this paper.

In recent years, the Alternaria blight disease has become a menace to the gingelly cultivators in Tamil Nadu. No detailed investigations of this serious disease have been made either in India or elsewhere, ever since the discase was recorded in North Caucasus (Kvashina, 1928). Hence studies were undertaken on various aspects of the disease and the results are presented in the paper.
O MACHISMO ESTRUTURAL REFORÇADO PELOS EFEITOS DO AGENDAMENTO E ENQUADRAMENTO: A COBERTURA MIDIÁTICA DO CASO SANDRA MARA FERNANDES
Authors: Netto Miguel Rodrigues , Oliveira Maria Heloisa Soares de , Cruz Ryan Chagas da
Published: October 2023

Este artigo visa demonstrar elementos constitutivos do machismo estrutural na sociedade brasileira evidenciados pela cobertura jornalística dispensada ao caso da lojista Sandra Mara Fernandes que sob efeito de um surto psicótico manteve relações sexuais dentro de seu carro com o morador em situação de rua Givaldo Alves em março de 2022 em Planaltina, Distrito Federal. O objetivo é evidenciar como os veículos de comunicação seguem a rotina produtiva da teoria de newsmaking e que a partir dos efeitos da agenda-setting e framing contribuem para a solidificação de uma cultura machista de exaltação do homem e condenação da mulher em relação a sexualidade. Utilizamos também dos
conhecimentos da análise do discurso para encontrar marcas textuais que validam essa hipótese. Como resultados lançamos um olhar sobre a prática profissional e a ética do jornalismo na exposição de vidas que tem muita dificuldade de se reestabelecer após uma exposição em nível nacional.
