Purpose The purpose of this study to establish what demographic characteristics (gender, generations and organisational tenure) play a role in employee perceptions of organisational culture, commitment and identification in Russian public organisations. Design/methodology/approach The data were collected electronically from 248 employees of two public organisations. Three questionnaires were used. Findings Organisational tenure plays a central role in the way how employees perceive organisational culture; tenure also shapes the levels of both commitment and identification. The specific finding of Russian settings is that the longer employees work for a company, the lower the levels of psychological attachments they demonstrate, while it is not the case for some existing international results. The other findings correspond with those in international studies, in which women were more psychologically attached to the organisation and showed a higher level of identification and lower rates of negative forms of this concept than men did. The older the employees are, the higher the level of identification they express. Practical implications Managers working in Russian settings can struggle with engaging and retaining employees. Understanding the demographic effects can help alleviate these challenges. Originality/value Based on empirical findings, this paper contributes to the literature on organisational socialisation by providing evidence of the damaging effects of the length of organisational tenure on psychological attachment to the company (in the form of commitment and identification). Additionally, tenure is the shaping factor of employee perception of organisational culture.

Demographic Effects

Abstract Beef genotypes and diets can improve the eating quality and consistency of beef. A 2-yr study was conducted to evaluate the effects of beef genotypes and diet on consumer acceptability of beef. Steaks were from Red Angus (RA) and RA x Akaushi (AK) crossbreed, fed one of two finishing systems: grazing (GRASS) and feedlot (GRAIN). Consumers (n = 105 in each year) evaluated cooked steaks for flavor, tenderness, juiciness, and overall acceptability using a 9-point hedonic scale. Demographical information was collected and used as covariates in the statistical model. There was no difference in sensory attributes (P > 0.05) between the genotypes, except that steaks from AK tended to be juicier than RA (P = 0.06). Sensory attributes were scored better in GRAIN than GRASS beef (P < 0.01) for all variables. There was a genotype by system interaction for flavor (P = 0.02), where beef from RA had a lower flavor rating in GRASS than in GRAIN, and no difference was observed for AK. Demographic effects showed that gender and beef consumption location had significant effects on flavor. Flavor scores were higher for females than males (6.1 vs 5.7, P = 0.02), and higher from consumers who eat beef in restaurants than consumers who do not eat beef in restaurants (6.6 vs 5.3, P < 0.01). Juiciness scores were impacted by the frequency of beef consumption. Panelists who eat beef once every 2–3 weeks rated the steaks juicier than those who eat beef once every 2–3 months (6.5 vs 4.3, P = 0.04), and consumers who eat grass-fed beef twice a year rated the steaks worse than those who eat it less than once a year (P = 0.02). Our results suggest that the beef finishing system had a marked impact on consumer acceptability, and AK might produce meat juicier than RA. Some demographic factors may influence consumer perceptions of beef.

Abstract Dams are a major contributor to the historic decline and current low abundance of diadromous fish. We developed a population viability analysis to assess demographic effects of dams on diadromous fish within a river system and demonstrated an application of the model with Atlantic salmon in the Penobscot River, Maine. We used abundance and distribution of wild- and hatchery-origin adult salmon throughout the watershed as performance metrics. Salmon abundance, distribution to upper reaches of the Penobscot watershed, and the number and proportion of wild-origin fish in the upper reaches of the Penobscot watershed increased when dams, particularly mainstem dams, were removed or passage efficiency was increased. Salmon abundance decreased as indirect latent mortality per dam was increased. Salmon abundance increased as marine or freshwater survival rates were increased, but the increase in abundance was larger when marine survival was increased than when freshwater survival was increased. Without hatchery supplementation, salmon abundance equalled zero with low marine and freshwater survival but increased when marine and freshwater survival rates were increased. Models, such as this one, that incorporate biological, environmental, and functional parameters can be used to predict ecological responses of fish populations and can help evaluate and prioritize management and restoration actions for diadromous fish.
