The Relationship

AbstractWe examine how a firm’s productivity level, wage level and productivity–wage gap are related to the age composition of its employees. Panel data of Norwegian firms in the following three sectors are used: the manufacturing sector, the WRT (wholesale and retail trade, repair of motor vehicles and motorcycles) sector, and the PST (professional, scientific and technical activities) sector. Three hypotheses are formulated: a firm’s productivity level is negatively affected by its proportion of the oldest workers (H1), a firm’s wage level is negatively affected by its proportion of the youngest workers, and positively affected by its proportion of the oldest workers (H2), and a firm’s productivity–wage gap is positively affected by its proportion of the youngest workers, and negatively affected by its proportion of the oldest workers (H3). Based on GMM regression in first differences, the estimation results give some support for (a) the hypothesis H1 for the WRT sector, but no support for the manufacturing and PST sectors, (b) H2 for the manufacturing and PST sectors, but little support for the WRT sector, and (c) H3 for the PST sector, but no support for the manufacturing and WRT sectors. The GMM results show that a firm’s productivity–wage gap is positively affected by the proportion of the youngest age group in the PST sector, while there is a non-significant effect in the manufacturing and WRT sectors. The proportion of the oldest age group has a non-significant effect on this gap in each of the three sectors. The results indicate that there is no clear evidence of an age-related productivity–wage gap.

The Relationship

Vitamin D requirements are thought to vary with age, but there is little comparative evidence for this. One goal in establishing a vitamin D requirement is to avoid secondary hyperparathyroidism. We studied 1741 euthyroid, thyroid clinic outpatients without evidence of calcium abnormalities, ranging in age from 19 to 97 yr, whose serum and urine had been analyzed for calcium, vitamin D, and parathyroid status. We found no effect of age on the 25-hydroxyvitamin D [25(OH)D] concentration associated with specific vitamin D intakes, and there was no relationship between 25(OH)D and 1,25hydroxyvitamin D [1,25(OH)2D]. In every age group, serum 1,25(OH)2D declined with increasing creatinine (P < 0.001). What changed with age included creatinine, which correlated with 25(OH)D (r = 0.146, P < 0.001) only in the youngest age group (19–50 yr) but not in the older age groups (P > 0.1). Creatinine did not correlate with PTH in the youngest age group, but the relationship became significant as age increased (e.g. for the elderly, r = 0.365, P < 0.001). Linear regression of log PTH vs. log 25(OH)D agreed with the natural shape of the relationship observed with scatterplot smoothing, and this showed no plateau in PTH as 25(OH)D increased. We compared PTH concentrations among age groups, based on 20 nmol/liter increments in 25(OH)D. Mean PTH in adults older than 70 yr was consistently higher than in adults younger than 50 yr (P < 0.05 by ANOVA and Dunnett’s t test). PTH levels of the elderly who had 25(OH)D concentrations greater than 100 nmol/liter matched PTH of younger adults having 25(OH)D concentrations near 70 nmol/liter. This study shows that all age groups exhibit a high prevalence of 25(OH)D insufficiency and secondary hyperparathyroidism. Older adults are just as efficient in maintaining 25(OH)D, but they need more vitamin D to produce the higher 25(OH)D concentrations required to overcome the hyperparathyroidism associated with their diminishing renal function.

Social Identity Approach

Due to demographic changes, age diversity is growing in the workplace, creating a potential challenge to social integration. However, who is most affected by working with colleagues of different ages and when is being dissimilar in age from others more likely to hinder organisational identification? Drawing on relational demography and on the social identity approach, we suggest that certain individual and contextual conditions can lead employees to react to greater age dissimilarity by reducing their psychological attachment to the organisation. We propose that negative age stereotypes and perceived age-related treatment affect the salience of age as a social category for employees and threaten their age group identity, thereby creating conditions in which age dissimilarity might hinder organisational identification. We therefore examine the moderating effects of negative age stereotypes and perceived age-related treatment on the relationship between age dissimilarity and organisational identification in a sample of 434 schoolteachers from 16 schools in Italy. Findings show that age dissimilarity per se is not sufficient to hamper employees’ identification with the organisation. However, it has detrimental effects when employees hold negative age stereotypes and/or perceive an unfair organisational treatment towards their own age group. Implications for research are discussed along with practice implications.

Abstract Subjective cognitive decline (SCD) is a construct of high interest in aging and dementia because individuals endorsing it are at higher risk of developing cognitive problems. It is unclear how individuals arrive at the judgement that they have SCD. Here we aimed to understand which SCD symptoms give rise to the perception of decline as older adults age. Community-dwelling adults (N=494, mean age=63.6, SD=5.44), completed the Subjective Cognitive Decline Questionnaire (SCD-Q) online, using an online crowdsourcing site. The SCD-Q consists of one global question regarding self-perceived decline (yes/no) and 24 questions about everyday functioning which we utilized to form a memory, language, and executive functioning domain score, higher for greater perceived decline. Logistic regression revealed that memory and language domains predicted the likelihood of endorsing SCD for adults aged >64 (Memory: OR=1.76, CI=1.47-2.05; Language: OR=1.66, CI=1.30-2.02). Only the memory domain predicted the likelihood of endorsing SCD for adults <63 (OR=2.69, CI=2.35-3.02). Executive functioning domain scores did not play a role in the relationship between SCD likelihood in either age group. The higher the self-perceived memory or language decline, the more likely older adults are to conclude they have SCD. Our results suggest there is an age-related trajectory in how people evaluate their cognition, with younger people only considering memory and older people considering both memory and language. Clinicians should be aware of this trajectory when examining patients with SCD. Executive functions should be specifically queried because they may not emerge from older adults’ self-reported cognitive problems.

With aging, a portion of cells, including mesenchymal stem cells (MSCs), become senescent, and these senescent cells accumulate and promote various age-related diseases. Therefore, the older age group has become a major population for MSC therapy, which is aimed at improving tissue regeneration and function of the aged body. However, the application of MSC therapy is often unsatisfying in the aged group. One reasonable conjecture for this correlation is that aging microenvironment reduces the number and function of MSCs. Cellular senescence also plays an important role in MSC function impairment. Thus, it is necessary to explore the relationship between senescence and MSCs for improving the application of MSCs in the elderly. Here, we present the influence of aging on MSCs and the characteristics and functional changes of senescent MSCs. Furthermore, current therapeutic strategies for improving MSC therapy in the elderly group are also discussed.

The article pays attention to the relation between capital equipment of labor and wage levels on the example of the Czech regions. Its main aim is to assess the relationship of the capital equipment of labor (expressed in terms of foreign direct investment and hours worked) to the wage level using correlation analysis, as well as the relationship of the capital equipment of labor and productivity in the regions of the Czech Republic. In addition, the validity of the relation “labor productivity is higher than the wage level” is verified using a comparison of standardized values of the indicators. The results show a high spatial dispersion of foreign direct investment in the Czech Republic, caused mainly by the Prague region. The positive correlation between the capital equipment of labor and wage levels, but also productivity, is statistically significant in the Czech regions. The problem of most Czech regions is the situation when the wage level exceeds the productivity level. Thus, the capital equipment of labor should firstly have a positive effect on the unit performance of labor, which would be rightly followed by increasing wages.

Abstract. Identifying pilot attributes associated with risk is important, especially in general aviation where pilot error is implicated in most accidents. This research examined the relationship of pilot age, expertise, and cognitive functioning to deviations from an ideal circuit trajectory. In all, 54 pilots, of varying age, flew a Cessna 172 simulator. Cognitive measures were obtained using the CogScreen-AE ( Kay, 1995 ). Older age and lower levels of expertise and cognitive functioning were associated with significantly greater flight path deviations. The relationship between age and performance was fully mediated by a cluster of cognitive factors: speed and working memory, visual attention, and cognitive flexibility. These findings add to the literature showing that age-related changes in cognition may impact pilot performance.

Macroeconomic Indicator

Subject. The working time of workers at any stage of economic development is a value reflecting the level of labor productivity. Any progress in productivity contributes to changes in the volume of labor costs and the number of employed. Depending on the relationship between the total volume of labor costs and the number of employed, the duration of working time per one worker may change (it may increase, decrease, or remain unchanged). Objectives. The study aims to confirm the importance of such a macroeconomic indicator as the number of employed in varying working hours. Methods. The study rests on the comparative analysis of countries with developed economies based on some indicators like dynamics of the working time fund, dynamics of the number of employed, average number of hours worked during the year per employee, etc. The analyzed timespan is 25 years (from 1991 to 2016). Results. The comparative analysis revealed that in the non-production sphere and the economy as a whole the macroeconomic determinants correlate so that the length of working time per worker reduces. When considering the analysis results for the manufacturing sector, no single trend was identified. Conclusions. One of the key factors affecting the change in working hours is the number of employed. The relationship between the working time fund and the number of employed directly determines the dynamics of working time per worker.

This study intends to find out the mediating effect of organisational culture on the relationship between information system and sustainable performance of manufacturing sector in UAE. This study used AMOS-SEM software to develop mediation model that linking the mediating relationships between Information System, Organisational Culture and Sustainable operation Performance. Data was collected through questionnaire survey among the operation staff of Abu Dhabi manufacturing companies. A total 250 questionnaires were distributed however 205 were returned and only 200 are valid which indicates a response rate of 80%. The analysis found that TPS has positive but not significant effect to SP; OIS has positive but not significant effect to SP; FMW has a positive and significant effect on SP; SDS has a negative and not significant effect to SP and SP has positive but not significant effect OC. For the path relationship between the four exogenous variables (TPS, OIS, SDS, and FMW) and the mediator variable (OC), the results are TPS has positive and significant effect to OC; OIS has positive but not significant effect to OC; FMW has positive and significant effect to OC and SDS has positive and not significant effect to OC. Collectively, the five exogenous constructs (TPS, OIS, SDS, FMW and OC) explained 89% variation in operational performance and 86% of the variation in organisational culture. However, for a mediator, it was found that OC has no significant mediating effect on the relationship between TPS and SP; OC has no significant mediating effect on the relationship between OIS and SP; OC has no significant mediating effect on the relationship between SDS and SP and OC has no significant mediating effect on the relationship between FMW and SP. it can be concluded that there is a positive relationship between information system dimensions and operational performance. However organizational culture has no contributing any mediating effect to the relationship. These findings have contributed to the body of knowledge and could be shared among the UAE manufacturing practitioners.

The light industry is an important inter-sectoral segment and a chain of individual production areas. The purpose of the article is to carry out a comparative assessment of the cross-sectoral linkages of light industry of Ukraine with some EU countries and to prepare relevant analytical conclusions. The research revealed that the largest consumers of light industry products in 2013-2017 in Ukraine were the industries that belonged to this type of industrial activity (textile, clothing, leather and other materials), as well as the trade, furniture industry, public administration, and defense. The key problem for the functioning of the Ukrainian light industry is its high import dependence. In particular, the share of imports in intermediate consumption of light industry of Ukraine in 2017 was almost 60%. The share of imports in the expenditures of the Ukrainian light industry was almost 49%. The production activities of light industry in Ukraine use products of many ECs, but the main suppliers of raw materials and components are: textile production, production of clothing, leather, and other materials; production of chemicals and chemical products; wholesale and retail trade; supply of electricity, gas, steam, and air conditioning. In 2017, these four sectors totaled 70.74%. The following types of industrial activity in Ukraine have a significant potential for increasing output: production of rubber and plastic products; production of motor vehicles, trailers and semi-trailers; production of other vehicles; public administration and defense; compulsory social security; health care and social assistance. The further development and improvement of the technological level of Ukrainian light industry products requires greater integration of the latter with the trade sector. However, the trade sector in Ukraine requires a thorough “unshadowing”, i.e. legalization of all operations.
