PurposeAfter the novel coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization in March 2020, its devastating effects began to be closely monitored all over the world. The new order that emerged due to the fight against the virus soon began to affect all our habits and behaviours. The fact that food consumption is vital for human well-being makes this an important area to investigate in terms of the impact of COVID-19. This research was carried out to investigate the changes in consumers' food consumption behaviour and habits during the COVID-19 pandemic and determine the factors that explain these changes.Design/methodology/approachIn line with the recommendations for social distancing under pandemic conditions, the empirical data were collected via computer-assisted telephone interviewing (CATI). The participants were 1,023 individuals living in the major cities of the seven regions of Turkey. An ordered probit regression model was used to estimate the attitudes related to the changes in food consumption behaviour and habits, and descriptive statistics are provided to show the current food consumption and purchase situation.FindingsThe results showed that the changes in food consumption behaviour and habits due to the pandemic were related to price increase concerns, stockpiling, awareness of food waste, safety and excessive, food access concerns, natural/organic food preferences and packaging of foods. Moreover, the participants tended to prepare food at home and preferred food that was popular with other consumers. Consumers mainly bought food from discount stores and local grocery stores and consumed fresh vegetables and fruits, animal-based products, cereals and pulses.Originality/valueThe current study contributes to knowledge regarding the effects of the coronavirus pandemic on food consumption behaviour by using a predictive model and provides behavioural estimations by using a countrywide questionnaire. The results show that the pandemic affects food consumption routines and food perspective of consumers in various ways.

The aim of this study is to estimate the soil temperatures of a target station using only the soil temperatures of neighboring stations without any consideration of the other variables or parameters related to soil properties. For this aim, the soil temperatures were measured at depths of 5, 10, 20, 50, and 100 cm below the earth surface at eight measuring stations in Turkey. Firstly, the multiple nonlinear regression analysis was performed with the "Enter" method to determine the relationship between the values of target station and neighboring stations. Then, the stepwise regression analysis was applied to determine the best independent variables. Finally, an artificial neural network (ANN) model was developed to estimate the soil temperature of a target station. According to the derived results for the training data set, the mean absolute percentage error and correlation coefficient ranged from 1.45% to 3.11% and from 0.9979 to 0.9986, respectively, while corresponding ranges of 1.685-3.65% and 0.9988-0.9991, respectively, were obtained based on the testing data set. The obtained results show that the developed ANN model provides a simple and accurate prediction to determine the soil temperature. In addition, the missing data at the target station could be determined within a high degree of accuracy.

Hake (Merluccius merluccius) and lizardfish (Saurida undosquamis) were caught seasonally at the northeastern Mediterranean Sea to determine their proximate compositions and fatty acid contents. Statistical (P < 0.05) differences among seasons were observed in the values of moisture, protein, lipid and ash. Saturated fatty acids and polyunsaturated fatty acids were the most abundant fatty acids in both species, with palmitic acid (C16:0), eicosapentaenoic acid (C20:5 n-3) and docosahexaenoic acid (C22:6 n-3). This research demonstrated that these species were characterized by low lipid content and were also a good source of unsaturated fatty acids. Therefore, hake and lizardfish, in terms of nutritional quality, could be recommended for human consumption.

This study describes the length-weight relationship (LWR) for Serranus hepatus from Iskenderun Bay, Northeastern Mediterranean, Turkey. A total of 202 individuals were caught from Iskenderun Bay, during the 2015-2016 fishing season. The total length ranged from 5.7-9.5 cm and body weight 2.23-12.19 g. Length-weight relationship was found as the W = 0.0172L 2.9664 (R 2 =0.84, F1,200=21.221, P < 0.001) and SEb= 0.091 (t-test: 32.706 p < 0.01). The types of growth were found isometric growth for all indivuduals of S. hepatus.

This paper focus on the seafood consumption attitudes and behaviours of the millennials (Generation Y) and non-millennials (Generation X, Baby Boomers and Silent Generation) comparatively. The data was collected from a face to face survey which was applied to randomly select 407 individuals in the city of Adana, Turkey in November 2016. As a result of factor analysis applied in the study, it was found that Millennials was significantly and inversely correlated with consumption of wild fish and freshwater fish. Non-millennial generation was inversely correlated with consumption of marine fish, freshwater fish and mussels and the correlation is insignificant. According to the results of the chi square test, it was determined that Millennials mostly preferred to consume fresh (unprocessed) fish. Mann-Whitney test results show that they value health and nutrition factors for consumption and there is a significant difference between these two factors. Besides, factors mainly effecting their purchase behaviour of seafood are directed to freshness, seasonality, place of purchase and wild-aquaculture product classification and there are significant differences between these factors. The fact that the Millennial’s average response to consumption and purchasing is higher indicates that they are more cautious.

ÖZETFutbolda şiddet olaylarının çıkmasında fanatik ve holigan olarak adlandırılan taraftarların payının büyük olmasına rağmen, genel taraftar kitlesinin şiddete eğilimli olması ve olaylara dahil olması, şiddetin daha büyük boyutlara ulaşmasında önemli rol oynamaktadır. Spor sahalarında yaşanan şiddet ve saldırganlık eylemlerinin gittikçe artan boyutlara ulaşması ve sokaklarda taraftarların polisle veya takımların taraftarlarının birbirleri ile çatışmaları toplumsal dokunun zedelenmesine neden olmaktadır. Yapılacak bilimsel çalışmalar ışığında düzenlemelerin yapılması, şiddet olaylarının önlenmesinde daha etkin bir yol sunacaktır. Bu çalışma ile, Adana ilinin en eski ve ezeli iki rakip takımı olan ve her karşılaşmalarında çıkan şiddet olayları ile anılan, Adanaspor ve Adana Demirspor futbol taraftarlarının demografik özellikleri ile şiddet eğilimlerinin ortaya konulması amaçlanmıştır. Çalışmanın bulgularında, Adana Demirspor taraftarlarının eğitim düzeylerinin yüksek ve daha fazla meslek sahibi oldukları, Adana spor taraftarlarının, daha genç ve daha çok öğrenci kitlesinden oluştuğu ve şiddet eğilimlerinin Adana Demirspor taraftarlarına göre daha fazla olduğu belirlenmiştir. Anahtar sözcükler: Adanaspor, Adana Demirspor, Sporda Şiddet VIOLENCE TRENDS OF ADANA DEMİRSPOR AND ADANASPOR SOCCER FANS ABSTRACTAlthough fans called as fanatics and hooligans have a large share concerning aggressive behaviors in football; the tendency to violence of general fan mass and their contribution to the cases have a significant role for the increase of violence to alarming levels. Gradual increase in the amount of violence and aggression in sports areas and the conflict between fans and police or the conflict between the opponent teams' fans bring forth damage to the social structure. Arrangements in the light of scientific studies will present a more effective way in preventing violence. In this study; the purpose is to expose the demographic characteristics and tendency to violence of the fans of two arch-rivals and the primal teams Adanaspor and Adana Demirspor in Adana Province. With the results of this study, it was determined that Adana Demirspor supporters have higher education level and have a higher employment level whereas Adanaspor supporters are young, mostly students and have more tendency to violence than Adana Demirspor fans.
