Abstract

The active and passive flow of information that this issue of WwOP has so far explored is all about the betterment of older people's lives. But how far can we drill down into the minutiae of an individual's life in order to make it better without being intrusive? Through the story of Dennis, Sam Bennett, Helen Sanderson and Gill Bailey now describe a method that is being refined to do just that.

Abstract

Purpose

To study the interface properties of anisotropic conductive adhesives (ACAs) and improve the electrical properties of ACA joints as a replacement for Sn/Pb solder in the electronics industry.

Design/methodology/approach

In this study, different types of self‐assembled monolayer (SAM) compounds were introduced into the interface between the metal filler and the substrate bond pad. The formation of these SAMs on gold and silver surface and their thermal stability were investigated by measuring the contact angles with water of these SAM coated surfaces. The SAM compounds used had either hydrophilic or hydrophobic tail groups, and included octadecanethiol (ODT), mercpatoacetic acid (MAA), 1,4‐benzenedithiol (dithiol) and malonic acid (acid M). Epoxy resins with two different curing temperatures were used as polymer matrices for the ACA formulations. The electrical properties of ACA joints containing these SAMs were studied by measuring their current‐voltage relationship.

Findings

The results show that SAMs can be successfully coated onto specific metal surfaces, depending on the affinity of their functional groups with the specific metal. The SAM treated ACA joints show much lower resistance at the same applied current than non‐treated joints, and the effect on the low curing temperature epoxy matrices was more significant. Nano‐Ag filled ACAs show more significant improvements in their electrical properties due to the greater surface area and higher surface energy of nano‐particles and consequently their higher thermal stability when coated with SAMs.

Originality/value

This paper is the first to use functional organic monolayers to enhance the interface properties of electrically conductive adhesives and, in particular, for ACAs.

Abstract

The second article of the “Library Bill of Rights” proclaims: “Libraries should provide materials and information presenting all points of view on current and historical issues. Materials should not be proscribed or removed because of partisan or doctrinal disapproval.” Keeping this article in mind, have librarians always adhered to it? Cal Thomas, vice president of the Moral Majority, does not think so. In Book Burning (1982), he accuses the liberal establishment of censoring the writings of conservatives. For too long, conservatives have been branded as the arch banners when, in fact, they have faced prohibitive treatment from liberals. Thomas insists that some liberal publishing houses do not want to bring out a work espousing conservative ideals no matter how well‐written it is. Liberal extremist groups pressure publishing houses to reject their manuscripts. Liberal critics dismiss their books in a few sentences or do not review them at all. The large bookstore chains fail to stock their books, therefore depriving the reading public of exposure to them. And Thomas' final regret is that librarians turn a cold shoulder to books by conservatives, excluding them from their collections and, more importantly, from the judgment of history.

Abstract

Purpose

This study aims to understand the asset and success factors that contributed to college completion of African American males who persisted through college. Only a dismal 22 per cent of African American males receive bachelor’s degrees compared to 41 per cent of White males (Kena et al., 2015).

Design/methodology/approach

The data were analyzed using interpretive phenomenological analysis. The authors interviewed two first-generation African-American males from rural backgrounds to capture their experiences of their process to college completion.

Findings

Themes, based in cultural capital theory, that impacted their college persistence were identified within their pre-college experiences, college experiences and post-college perceptions. Recommendations for helping rural African-American males attend and persist through college are offered.

Research limitations/implications

Only two participants from one predominately white institution in the southeastern USA were interviewed. Rural students from other geographical areas might have different backgrounds, challenges, assets and successes. Although the interview questions were based on relevant literature, they may not have covered all key aspects of the participants’ experiences. As in any qualitative study, biases of the researchers and research team may have influenced the results, although these were identified and shared before reading any of the transcripts and then discussed several times during the data analysis process.

Practical implications

Educators not only should try to address the cultural capital limitations of these men but also highlight and build on their cultural assets. These assets include familial and platonic individuals who see their potential for success and encourage them to attend college to become something better than what they see in their community, reverse role models who encourage youth to make different choices than they did, media-based examples of successful Black students, cultural messages of strength and determination (e.g. Million Man March) and the exhortation to be an example that other African-American boys could look up to.

Originality/value

This paper addresses the need for K-12 and higher education institutions to understand how to assist first-generation, rural African-American males in getting admitted to college, matriculating through college and graduating from college.

Abstract

Years ago, Henry D. Lloyd defined religion as being the “conscience in action.” The concept of religion is one which is indeed completely individualised in both perspective and importance. However, as Bailey (1983) observed, the very basis for theology lies in the explanatory power of religion when examined through the perspective of psychology. Byron (1988) saw a theological basis to the functions of management and entrepreneurship, linking these activities to the religious duty of stewardship.

Abstract

In 1996, there were about six hundred and fifty overseas‐trained medical doctors who had immigrated to New Zealand but were unable to practice their profession even though the New Zealand Qualifications Authority (NZQA) had assessed their medical qualifications as equivalent to similar qualifications in New Zea land. These immigrants were subjected to structural discriminator practices of the medical Council of New Zealand (MCNZ) by which qualified medical doctors from non BASIC (Britain, Australia, South Africa, Ireland and Canada) countries were not allowed to register as medical practitioners in New Zealand. The privilege conferred on the MCNZ by the 1968 Medical Practitioners Act allows it to be selective in re cognising medical qualifications. As a consequence of this discriminatory practice many of the foreign trained doctors were unemployed while others worked as process workers, taxi drivers, petrol pump dispensers and pizza deliverymen in the period covered in this article (Selvarajah, 1997). This article provides a case history between 1995 and 2000 on the concerns and conditions of a group of foreign‐trained medical professionals (doctors and specialists) whose application to settle in New Zealand was processed by the New Zealand government prior to June 1995.

Abstract

Purpose

The light detection and ranging sensor has been widely deployed in the area of simultaneous localization and mapping (SLAM) for its remarkable accuracy, but obvious drift phenomenon and large accumulated error are inevitable when using SLAM. The purpose of this study is to alleviate the accumulated error and drift phenomenon in the process of mapping.

Design/methodology/approach

A novel light detection and ranging SLAM system is introduced based on Normal Distributions Transform and dynamic Scan Context with switch. The pose-graph optimization is used as back-end optimization module. The loop closure detection is only operated in the scenario, while the path satisfies conditions of loop-closed.

Findings

The proposed algorithm exhibits competitiveness compared with current approaches in terms of the accumulated error and drift distance. Further, supplementary to the place recognition process that is usually performed for loop detection, the authors introduce a novel dynamic constraint that takes into account the change in the direction of the robot throughout the total path trajectory between corresponding frames, which contributes to avoiding potential misidentifications and improving the efficiency.

Originality/value

The proposed system is based on Normal Distributions Transform and dynamic Scan Context with switch. The pose-graph optimization is used as back-end optimization module. The loop closure detection is only operated in the scenario, while the path satisfies condition of loop-closed.

Abstract

Purpose

This study aims, a systematic review and meta-analysis, to evaluate the effects of folic acid (folate) on patients with depression.

Design/methodology/approach

Related articles were found by searching PubMed, SCOPUS, Web of science and Cochrane’s Library, from inception to January 2022. Weighted mean differences (WMD) were pooled using a random-effects model. Heterogeneity, sensitivity analysis and publication bias were reported using standard methods.

Findings

Pooled analysis of six randomized controlled trials revealed that folic acid supplementation decreased the depression score in the Beck Depression Inventory (WMD: −3.9; 95% CI: −5.3 to −2.4, p < 0.001) compared with control group, without heterogeneity (I2 = 0.0%, p = 1.000). It also lowered the depression score in the Hamilton (HAM) Depression Inventory (WMD: −3.5 mg/dL; 95% CI: −4.6 to −2.4, p < 0.001) compared with control group, with moderate heterogeneity (I2 = 71.8%, p = 0.007). Moreover, subgroup analysis showed that the folic acid supplementation reduced HAM in all subgroups. Meta-regression analysis demonstrated that there is no evidence of a significant linear relationship between dose and duration of folic acid supplementation and changes in HAM. Also, based on the non-linear dose response, no evidence of a relationship between dose and duration of folic acid supplementation and changes in HAM was found.

Originality/value

Folic acid supplementation could possibly have an effect on lowering depression in patients. However, the clinical trials thus far are insufficient for clinical guidelines and practice.

Abstract

Purpose

The purpose of this paper is to examine highly detailed “low-inference” transcripts (LITs) of peer coaching conversations, drawn from two public US high schools located in New York City, to explore the kinds of interactions that led peers to be more reflective about their instructional practice.

Design/methodology/approach

Using the constant-comparative method of analysis, highly detailed LITs of peer coaching conversations were analyzed to identify instances where peers had what the researchers identified as an “Aha!” moment, where the peer's prior belief or opinion about their instruction and/or planning shifted. Subsequent re-coding identified specific strategies that caused the shift.

Findings

Three kinds of interactions were identified as leading to an “Aha!,” all of which involved a thoughtful and strategic use of the LITs during the coaching conversation. Conversely, findings suggested that passive use of the transcripts was less successful.

Research limitations/implications

Future research should explore the nature and staying power of the shifts in peer thinking, and the extent to which these shifts lead to instructional changes and improved student performance.

Practical implications

–LITs are a promising tool for instructional coaching. The evidence suggests when in the hands of a skilled coach the transcripts can shift teachers’ thinking in ways that are likely to improve instructional practice and thus student outcomes.

Originality/value

This study highlights the value of pairing strategic and thoughtful peer coaching with highly detailed LITs, and identifies specific kinds of interactions that lead to shifts in thinking about instruction.
