The conceptualisation of Employee Voice in Permacrisis: A UK Perspective

Research on the topic of employment relations often adopts analytical frameworks related mainly to the concept of ‘voice’. While originally defined as the effort to effect change by Albert Hirschman, the meaning and conceptualisations of the term ‘voice’ have evolved over the years. Later writers such as Freeman and Medoff describe the concept from the point of view of union monopoly of representation, i.e., union articulation of workers’ concern. In this chapter, we present a synthesis and overview of some of the early conceptualisations of employee voice and unionism in the United Kingdom. Our goal extends beyond simply sketching or cataloguing the historical analysis around voice, to using this analysis as an instrument for understanding the current state and projecting into the future of employee voice and unionism in the United Kingdom. The chapter reveals that the concept of voice has been significantly reinvented by modern-day scholars. The chapter will heavily depend on a review of extant literature. It would, however, be impossible to synthesise the entire literature on voice in this short chapter. Hence, there will be a significant focus on the United Kingdom experience and authors, howbeit, other authors based elsewhere may be selectively included. The study concludes that though employee voice is relevant today, in most cases it only serves the interest of management and where this is not the case management hardly pays any attention to it. The study revealed further that during permacrisis, there is little or no attempt on the part of the management to attention to or implement the demand expressed in employee voice

Evidence from North Carolina shows that immigrant students with limited English have a very minor impact on native students’ performance

Much of the recent concern about undocumented immigration into the U.S. can be linked to the perceived burden that these immigrants may create on the public education system. But is this really the case? Through analyzing detailed information on the performance of students in North Carolina, Timothy M. Diette and Ruth Uwaifo Oyelere find that the presence of students with limited English does have a negative, though small, effect on the math and reading achievement of natives that are male and black. They argue, however, that these effects are so small as not to warrant policy interventions

Gender and Race Heterogeneity: The Impact of Increases in Students with Limited English on Native Students' Performance

The influx of immigrants has shifted the ethnic composition of public schools in many states including North Carolina. Recent evidence from North Carolina suggests that increases in Limited English students' concentration have led to a slight decline in performance solely for students at the top of the achievement distribution. The heterogeneous peer effects by achievement level lead us to explore in this paper whether the increased immigration has differential effects by gender and race. Utilizing fixed effects methods that allow us to address possible endogeneity with respect to the schools' students attend, we find heterogeneous peer effects of limited English students on natives' performance in math and reading. Specifically, we find no peer effects on white females but small negative effects on males and blacks on average

Do significant immigrant inflows create negative education impacts? Lessons from the North Carolina public school system

The influx of immigrants has shifted the ethnic composition of public schools in many states. Given the perceived negative impact of significant immigrant inflows, we are interested in investigating if these inflows into a school affect the academic performance of native students who remain. To address this question, we analyze education data from North Carolina, a state that has experienced a significant immigrant influx in the last two decades. We focus on the share of the English Language Learners in the student population for students between fourth and eighth grade over the period from 1999 to 2006 and the potential effects of the presence of these students on the level of achievement in math and reading for native students. Our analysis suggests some evidence of immigrant peer effects though the effects are heterogeneous. Specifically, we find some evidence of positive effects among those in the middle and bottom portions of the achievement distribution while we find small negative effects at the top of the distribution

Advancing AI education: Assessing Kenyan in-service teachers' preparedness for integrating artificial intelligence in competence-based curriculum

This is the final version. Available from Elsevier via the DOI in this record. Data availability: Data will be made available on request.With the advancement of technology, emerging technologies like Artificial Intelligence (AI) have also been growing rapidly and becoming more common than ever before. Kenya has taken tremendous steps in adopting the use of emerging technology in different sectors of the economy. In realization of the need to have a skilled digital workforce to develop solutions using these emerging technologies, Kenya has undertaken curriculum reforms and introduced the Competency-Based Curriculum (CBC) which has included digital literacy and coding in elementary school. Furthermore, computer science has been introduced in Junior Secondary School. In view of these changes, teachers should be adequately prepared with knowledge, skills, and attitudes to effectively teach these new technologies. However, in Kenya, AI was not and still is not part of the teacher training curriculum. Additionally, there are inadequate professional development opportunities in AI for both pre-service and inservice teachers since AI is not part of the CBC curriculum. That notwithstanding, it is inevitable for teachers in the current world to introduce AI to learners. Therefore, this study’s objectives were to assess the confidence in AI, attitudes toward AI, AI ethics, subjective norms, perceived threats, and the readiness to teach AI among Kenyan K-12 in-service teachers and to assess how these factors influence their readiness to teach AI. To achieve these objectives, this study employed a quantitative research methodology by administering a survey using Google Forms to a random sample of 308 teachers from different grades from 37 out of 47 counties in Kenya. The findings showed that confidence in AI, AI ethics and subjective norms significantly influenced AI readiness while attitude towards AI and perceived threats did not significantly influence AI readiness. These results are significant in providing a basis for education policy change on AI education in Kenya, such as transforming the teacher training curriculum to include AI and designing AI professional development programs for in-service teachers to ensure they are well-equipped to teach AI.University of Exete

The Role of Race and Birth Place in Welfare Usage among Comparable Women: Evidence from the U.S.

There is evidence that women are more likely to live in poverty than men. Given the fact that the poor are more likely to use welfare, it becomes useful to consider welfare usage among women. A-priori welfare programs are set up in such a way that welfare usage should be based primarily on economic needs and health concerns. However, it is possible that an individual's experiences could affect their perception and preferences for using government assistance. In this scenario, differences in welfare usage will exist for individuals with similar characteristics but different experiences. We explore this possibility among women and investigate if race/ethnicity and birthplace still have a role to play in the decision to use welfare even after controlling for income, health and other demographic factors like employment. We find that race does not matter for welfare usage among comparable women. In addition, we do not find any significant differences in welfare usage among women based on birthplace - suggesting that comparable naturalized and native born women share similar preference for welfare. The only exception is women born in US territories. Our results suggest that among comparable women, women born in U.S territories seem to be more inclined to welfare usage in comparison to US born White women

Effect of Climate Change on Arable Crop Farmers Productivity in Ibarapa Centra Local Government Area of Oyo State Nigeria

The study was an analysis of the Effect of climate change on arable crop farmers’ productivity in ibarapa central local government of Oyo state, Nigeria.  Primary data were collected using structured interview guide, administered on 100 arable crop farmers using multistage sampling technique. Data collected were analyzed using descriptive statistics (frequency and percentage) and inferential (partial correlation) statistical tools. The result showed that the mean age was 47.6years while 97% were married. However 97.00% of the arable crop farmers reported to have had malaria attack occasionally within the last10 years and 83.00% in the last five years  while 64% reported malaria occurrence within the last one year.Majority (83.00%) of the respondent stated that erratic rainfall as compared to other causes  had more effect on their productivity while just a few (7.00%) of the respondent claimed that low heat was the cause of their low productivity. The hypothesis tested revealed that the socioeconomic characteristics of the arable crop farmers such as age (0.7490), sex (0.3200), household size (0.4580), income (0.5500) and educational status (0.3240) had significant positive relationship with their levels of productivity. It was recommended that the arable crop farmers should form farmers association to pool resources together to acquire irrigation gadgets so as to alleviate the problem of erratic nature of rainfall in the area and Nigerian Meteorological Agency (NIMET) should be more alive to her weather forecast responsibilities in the area of using diverse languages of the people in the Nigerian agricultural zones.

PEG Branched Polymer for Functionalization of Nanomaterials with Ultralong Blood Circulation

Nanomaterials have been actively pursued for biological and medical applications in recent years. Here, we report the synthesis of several new poly(ethylene glycol) grafted branched-polymers for functionalization of various nanomaterials including carbon nanotubes, gold nanoparticles (NP) and gold nanorods (NRs), affording high aqueous solubility and stability for these materials. We synthesize different surfactant polymers based upon poly-(g-glutamic acid) (gPGA) and poly(maleic anhydride-alt-1-octadecene) (PMHC18). We use the abundant free carboxylic acid groups of gPGA for attaching lipophilic species such as pyrene or phospholipid, which bind to nanomaterials via robust physisorption. Additionally, the remaining carboxylic acids on gPGA or the amine-reactive anhydrides of PMHC18 are then PEGylated, providing extended hydrophilic groups, affording polymeric amphiphiles. We show that single-walled carbon nanotubes (SWNTs), Au NPs and NRs functionalized by the polymers exhibit high stability in aqueous solutions at different pHs, at elevated temperatures and in serum. Morever, the polymer-coated SWNTs exhibit remarkably long blood circulation (t1/2 22.1 h) upon intravenous injection into mice, far exceeding the previous record of 5.4 h. The ultra-long blood circulation time suggests greatly delayed clearance of nanomaterials by the reticuloendothelial system (RES) of mice, a highly desired property for in vivo applications of nanomaterials, including imaging and drug delivery

Coffee consumption is associated with a reduced risk of colorectal cancer recurrence and all-cause mortality

Coffee consumption has been associated with a reduced risk of developing colorectal cancer (CRC). However, it is not clear whether coffee consumption is related to CRC progression. Hence, we assessed the association of coffee consumption with CRC recurrence and all-cause mortality using data from a prospective cohort study of 1719 stage I–III CRC patients in the Netherlands. Coffee consumption and other lifestyle characteristics were self-reported using questionnaires at the time of diagnosis. We retrieved recurrence and all-cause mortality data from the Netherlands Cancer Registry and the Personal Records Database, respectively. Cox proportional hazard regression models with and without restricted cubic splines were used to calculate hazard ratios (HR) and 95% confidence intervals (CI) adjusted for age, sex, education, smoking status, cancer stage and tumor location. We observed 257 recurrences during a 6.2-year median follow-up and 309 deaths during a 6.6-year median follow-up. Consuming more than 4 cups/d of coffee compared to an intake of &lt;2 cups/d was associated with a 32% lower risk of CRC recurrence (95% CI: 0.49, 0.94,). The association between coffee consumption and all-cause mortality was U-shaped; coffee intake seemed optimal at 3–5 cups/d with the lowest risk at 4 cups/d (HR: 0.68, 95% CI: 0.53, 0.88). Our results suggest that coffee consumption may be associated with a lower risk of CRC recurrence and all-cause mortality. The association between coffee consumption and all-cause mortality appeared nonlinear. More studies are needed to understand the mechanism by which coffee consumption might improve CRC prognosis.</p
