Abstract
Purpose
The purpose of this paper is to describe and explain trauma-informed approaches (TIAs) to mental health. It outlines evidence on the link between trauma and mental health, explains the principles of TIAs and their application in mental health and explores the extent to which TIAs are impacting in the UK.
Design/methodology/approach
The approach is a conceptual account of TIAs including a consideration of why they are important, what they are and how they can become more prevalent in the UK. This is supported by a narrative overview of literature on effectiveness and a scoping of the spread of TIAs in the UK.
Findings
There is strong and growing evidence of a link between trauma and mental health, as well as evidence that the current mental health system can retraumatise trauma survivors. There is also emerging evidence that trauma-informed systems are effective and can benefit staff and trauma survivors. Whilst TIAs are spreading beyond the USA where they developed, they have made little impact in the UK. The reasons for this are explored and ways of overcoming barriers to implementation discussed.
Originality/value
This paper – authored by trauma survivors and staff – describes an innovative approach to mental health service provision that, it is argued, could have immense benefits for staff and service users alike.

Abstract
Refers to the history of the maritime sale of goods which resulted in a bill of lading, representing goods at sea in a ship. Attempts to determine whether or not a bill of lading is a negotiable instrument if it is characterized by such words as to order or to bearer. Compares US, Greek and English law and finds that English law is not in line with US and Greek law. Refers to the English Carriage of Goods by Sea Act (COGSA) 1992. Claims that differences in law may cause some problems for international trade and mentions the European Commission’s project to examine the feasibility of electronic bills of lading.

Abstract
Investigates the theory and practice of negotiation through studying British managers in a role playing situation; observations then formed the basis of this questionnaire survey, which was sent to 300 UK managers, and follow‐up interviews were carried out with 30 managers. Refers to earlier research conducted by the same authors and explains how this research builds on their previous findings. Explains the methodology of this study. Reports on the use of teams in negotiating behaviour, the size of the teams, team preparation and formation, team roles, team management, acquiring information, understanding agreements, demonstrating a united front, establishing facts, attempting to split the opposition, exaggerating divisions in an opposing team, tactics, and the use of adjournments. Concludes that smaller teams, consisting of people used to working together, are perceived to be more effective. Highlights the areas where teams new to negotiations or working together should focus their attention. Suggests areas for further research.

Abstract
Purpose
Recent advancements in the domain of smart communication systems and technologies have led to the augmented developments for very large scale integrated circuit designs in electro-magnetic applications. Increasing demands for low power, compact area and superior figure of merit–oriented circuit designs are the trends of the recent research studies. Hence, to accomplish such applications intended for optical communications, the transimpedance amplifier (TIA) was designed.
Design/methodology/approach
In this research work, the authors present a multi-layer active feedback structure which mainly composes a transimpedance stage and a gain stage followed by a low pass filter. This structure enables to achieve improved input impedance and superior gain. A simplified cascaded amplifier has also been designed in a hierarchical topology to improvise the noise effect further. The proposed TIA has been designed using Taiwan Semiconductor Manufacturing Company 45 nm complementary metal oxide semiconductor technology. Moreover, the thermal noise has been analyzed at −3 dB bandwidth to prove the reduction in thermal noise with increase in frequency for most of the devices used in the designed circuit.
Findings
The proposed differential TIA circuit was found to obtain the transimpedance gain of 50.1 dBO without applying any external bias current which is almost 8% improvised as compared to the conventional circuit. In addition to this, bandwidth achieved was 2.15 GHz along with only 38 W of power consumption, which is reasonably 100 times improvised in comparison of conventional circuit. Hence, the proposed differential TIA is suitable for the low power optical communications applications intended to work on low supply voltage.
Originality/value
The designed work is done by authors in university lab premises and is not copied from anywhere. To the best of the authors’ knowledge, it is 100% original.

Abstract
Purpose
The purpose of this paper is to design a very low‐noise transimpedance amplifier (TIA) for a novel multi‐pixel CMOS photon detector which performs secondary electron (SE) detection in the scanning electron microscope (SEM).
Design/methodology/approach
The TIA, which is implemented with three‐stage push‐pull inverters, is optimised using a nomograph technique developed in MATLAB. SPICE simulations are conducted to verify the results generated from MATLAB. Important performance figures are obtained experimentally and these measurements are compared with simulation results.
Findings
A low‐noise TIA fabricated in a standard 0.35 μm CMOS technology was tested. Experimental results obtained show that the TIA connected to a photodiode with a junction capacitance of 0.8 pF can carry out its task effectively with a transimpedance gain of 126.9 dBΩ, a bandwidth of 9.8 MHz, an input‐referred noise of 2.50×10−13 A/√Hz and an SNR of 12.8. The power consumption of the TIA was 49.3 mW. These encouraging results have exhibited the potential of the circuit for use in the CMOS photon detector.
Originality/value
This paper presents a low‐noise transimpedance amplifier that is highly suitable to be used as a critical constituent block for the CMOS photon detector which aims to take over the role of photomultiplier tube in SE detection in the SEM. Solid‐state approaches have recently been reinvigorated for improving certain aspects of SE detection in scanning electron microscopy and this work has supported and contributed to the trend.

Abstract
Purpose
Diversity of people, knowledge and resources has been identified as a determinant of firms' growth. This paper focusses on innovation propensity as a critical dimension of firm's growth path, aiming to analyse the effects of the firm's horizontal educational diversity (HED) on the propensity to conduct different technological innovation activities (TIAs). In addition, considering the evidence showing that these effects are neither direct nor linear, the authors analyse the moderating role of the firm's organizational practices oriented to knowledge sharing (KS) on the association between HED and the adoption of TIAs.
Design/methodology/approach
Following the theoretical arguments of the resource-based view (RBV), the evolutionary economics and the dynamic capabilities approach and related empirical evidences, the authors proposed four hypotheses regarding the effect of HED on TIAs and the moderating role of work organization practices oriented to promote KS. Empirically, the authors calculated different HED diversity indexes capturing two basic dimensions: variety and balance. Hence, using instrumental variables and panel data techniques to control endogeneity biases, the authors tested the proposed hypotheses using a data set of Uruguayan manufacturing firms between 2004 and 2015.
Findings
In line with previous evidence, results showed idiosyncratic context effects. The authors found a robust, linear, positive and significant relationship between HED and TIAs, but the effect can only be consistently associated with the adoption of internal or external research and development (R&D) activities. Moreover, the moderating role of work organization practices oriented to promote KS is positive and significant when firms engage in TIAs. For technological innovations that only involve the acquisiton of technology (AT), a positive effect is also observed but always associated to organizational practices oriented to promote KS.
Originality/value
This paper revisits the analysis of workforce diversity for a relatively less explored context. This research contributes to the field by linking HED and work organization practices to understand firm's innovation propensity in a developing context. Moreover, while other studies have focussed only on top management or R&D team diversity, the authors have analysed the whole professional's workforce. It allows the authors to discuss the effects of diversity on innovation propensity in the light of the ongoing debate on the effects of innovation in employment.

Abstract
Purpose
A model of the relationships between individuals' perceptions of internet use and internet usage behaviors is presented and tested. The purpose of this paper is to propose that a lack of perceived responsiveness to on‐line communication is positively related to individuals' general resistance to use the internet as a communication information exchange medium, termed general internet apprehensiveness (GIA). Perceptions of GIA are negatively associated with on‐line information‐seeking behavior, and positively associated with individuals' resistance to or fear of using the internet for on‐line retail transactions, termed transactional internet apprehensiveness (TIA).
Design/methodology/approach
College‐aged students reported their attitudes about on‐line information seeking, on‐line purchasing, and their on‐line information seeking and purchasing behaviors. The model presented is tested with path analysis to assess the variables' interrelationships.
Findings
Ultimately, lack of responsiveness is positively related to GIA, GIA is negatively related to information‐seeking behavior, and TIA is negatively related to consumers' on‐line purchasing of goods and services.
Research limitations/implications
The student sample used in this study prevents us from making broad‐based generalizations. While students represent a large base of internet users and have been presented as a viable population to study in investigations for both academic audiences and marketing practitioners, future research will continue to benefit from more diverse samples of internet users.
Practical implications
This study offers hospitality professionals a better understanding of the elements that inhibit or encourage on‐line information seeking and purchasing behaviors.
Originality/value
This paper further defines the socio‐demographic factors that inhibit consumers from using the internet as both an information‐sharing tool and purchasing medium.

Abstract
Talks about the cultural aspects of negotiating in China and compares this with Western approaches. Focuses on cultural factors (and the dominant role of Confucianism), followed by steps in the negotiating process. Explains Confucian ethics and how that translates into everyday behaviour of how to treat and address other people. Points out that the Chinese will only do business with people they know and trust, so the importance of first building good personal relationships cannot be overstated. Suggests ways to make a good first impression, including attending banquets and other social occasions, although that opens up a further behavioural minefield. Recommends viewing doing business with the Chinese as a marriage contract based on old‐fashioned courting, rather than in the West, where entering a business relationship could be deemed the equivalent of a marriage of convenience.

Abstract
Discusses the Bill of Lading and its differences under UK, US and Greek law. Bases the paper on the fact that, under UK and US law, property in the goods sold passes from seller to buyer when the parties intend to pass it (regardless of whether or not delivery actually took place); whereas, under Greek law, ownership of goods passes from seller to buyer only if the intention to pass goods is supported by actual delivery. Asserts that this difference in national law causes problems in international trade. Explores the law in more depth, citing a number of cases and quoting legal precedents. Concludes that the intention of the parties concerned should be taken into consideration.

Abstract
Compares and contrasts the contractual roles of modern waybills against the traditional straight bills of lading in the context of Greek, US and English law. Chronicles the development of international lading bills; identifies the emergence of straight bills and waybills to ameliorate the logistical problems associated with order bills of lading. Discusses the legal status and contractual roles of these lading bills in the context the legislative provisions and associated case law in each of the three countries. Concludes that sea waybills (regulating marine transport of goods) and straight bills of lading have, in essence, the same contractual status, despite the confused and unconsolidated picture of international lading provisions and practices. Recommends measures ‐ involving amendments to English legislation ‐ to consolidate the regulation of international trade.
